Sirs,
I still wonder how the responder Mr Rajaram titled the response to the QA as
"agnatha vasam".
Whether he meant" Anjathavasam"? If so what reference it has with the subject?
As wrote earlier"Vayil thonniyathu Kothaikku pattu". What more to
write?Gopalakrishnan

Dear folks
As expected, the flesh-eating human culture-vulture masquerading as K Rajaram
ex-IRS 27125 cannot resist feeding on another human being such as Sri
Gopalakrishna.
The carcass-consuming predator/scavenger has no ideas of its own, but seizes
upon anything its victim has originated, and thereupon takes flight in the
cerulean skies shrieking its own version of the states of being in the universe.
Its ally-pally approach to its boot-licking consort YM Sarma, late Yaddanaapudi
Maarkendulu alias Markie,is visibly and radically different.

CULTURAL QA 01202526
CURIOUS QA – BASE QA FROM QUORA –Compiled
Q1 Whydon't house cats hunt chickens, even if the house cats are
wild?
KR Generally cats chase but never acts like a predator.Chickens
always play tricks but cats only threaten it as it happened today. Generally,
cats aren’t natural hunters ofchickens, especially adult ones. Cats are more
likely to hunt small prey likemice, birds, or insects. However, if a chicken is
young, injured, or weak, acat might go after it. Some cats may also show
curiosity toward chickens, butthey typically aren't as predatory toward them
as, say, foxes or hawks.
Q2 Howdoes the predator hierarchy differ across African regions?
KR: Thehierarchy of predators around the world can be looked at
from different anglesdepending on the type of predator (terrestrial, aquatic,
aerial), the foodchain in a particular ecosystem, and the specific niche each
predator fills.However, in general, there are some similarities and differences
in howpredators rank within ecosystems across the globe. Let me break it down
foryou:
General Hierarchy of Predators:
Apex Predators: These are at the top of the food chain,with no natural
predators of their own. Apex predators control populations ofother species,
helping maintain balance in ecosystems.
Terrestrial Examples: Lions, tigers, and polar bears.
Marine Examples: Great white sharks and killer whales(orcas).
Aerial Examples: Harpy eagles and some large hawks.
Mesopredators: These are mid-level predators that huntsmaller prey but may also
be preyed upon by apex predators. They can play animportant role in shaping
populations of prey species.
Terrestrial Examples: Coyotes, wolves (in someenvironments), bobcats, and wild
dogs.
Marine Examples: Smaller sharks, such as the reef shark.
Aerial Examples: Falcons and owls.
Opportunistic Predators: These predators can sometimeshunt but also scavenge or
steal food from others, often filling in the gapbetween apex and Mesopredators.
Terrestrial Examples: Jackals, hyenas (sometimesconsidered apex in some
environments), raccoons, and foxes.
Marine Examples: Sea gulls, some species of tuna.
Aerial Examples: Ravens, some crows.
Scavengers: While not strictly “predators” in thetraditional sense, scavengers
consume carcasses left behind by other animals,including apex predators. Some
scavengers can be opportunistic predators aswell.
Terrestrial Examples: Vultures, hyenas (alsomesopredators), crows.
Marine Examples: Certain species of crabs, seagulls, andother birds.
Aerial Examples: Vultures and certain species of hawks.
Differences Across Ecosystems:
Terrestrial vs. Marine vs. Aerial:
In terrestrial ecosystems, apex predators like lions andtigers are more common,
often with a pack structure (like wolves) influencingthe food web.
In marine environments, you have huge apex predators likekiller whales and
great white sharks, where the hunting dynamic involves bothphysical power and
hunting strategies.
Aerial predators like eagles or falcons have verydifferent hunting methods,
using speed, keen vision, and agility to catch prey.
Diet Specialization:
Some predators are specialists (e.g., the cheetah, whichprimarily hunts
gazelles), while others are generalists (e.g., wolves, whichwill hunt many
types of animals depending on what is available).
Niche Differences:
Predators might occupy a similar trophic level butspecialize in different prey
depending on their environment. For example, aforest environment might have
carnivores like wolves and owls, while agrassland might have lions and cheetahs
as apex predators.
Climate Influence:
Apex predators in the Arctic, like polar bears, haveunique hunting strategies
suited to cold, icy landscapes, while those intropical rainforests (e.g.,
jaguars) need to navigate dense foliage. The kindsof prey and how they hunt
differ significantly.
Key Similarities and Differences:
Similarities: Across ecosystems, apex predators sharecommon traits like power,
speed, intelligence, and the ability to dominatelower-level predators or prey.
Differences: The types of prey and hunting strategies varysignificantly
depending on the environment. For example, a hawk’s huntingstrategy is vastly
different from a shark’s or a lion’s, even though they allmay be apex predators
in their own ecosystems.
So while there arepatterns in predator hierarchies around the world,
differences certainly existbased on the environmental and ecological context.

Q3 Atwhat age does walking up and down stairs become too demanding
simply due toaging?
KR MrViswanath rite up is pretty Good. But lacks the reasons so
I explain it. Walkingup and down stairs can become more challenging as we age,
and the age at whichthis happens varies based on factors like overall health,
fitness level, andany existing medical conditions. However, there are general
trends:
1. Age-related Decline:
Late 60s to Early 70s: Many people start to notice stairclimbing becoming more
physically demanding in their late 60s to early 70s.This is often due to a
combination of reduced muscle mass, joint flexibility,and balance.
Mid-70s to 80s: As we age further, around the mid-70s to80s, physical decline
can become more noticeable, especially in people whohaven't been maintaining
regular physical activity. Strength, endurance, andjoint health might limit
one’s ability to climb stairs easily.
Factors ThatInfluence When It Becomes Demanding:
Muscle Mass andStrength: As people age, they naturally lose muscle mass (a
condition calledsarcopenia), which can make tasks like climbing stairs harder.
Joint Health:Osteoarthritis and other joint problems can make it painful to use
stairs. Thisespecially affects the knees and hips, which are crucial for stair
climbing.
Balance andCoordination: Aging can affect balance, making people more cautious
whennavigating stairs, which increases the difficulty.
CardiovascularHealth: If heart or lung function declines, tasks that require
sustainedenergy, like climbing multiple flights of stairs, might become more
taxing.
Weight and FitnessLevel: Those who maintain a healthy weight and regular
fitness routine maycontinue to find stairs manageable well into their 70s or
even 80s, while thosewho are less active may find them harder at a younger age.
When It Becomes Too Demanding:
For some, stairs become too demanding due to a combinationof these factors, and
it may not just be about a specific age but a gradualdecline over time. Some
people might need assistance with stairs in their 80s,while others might still
manage without issue in their 90s.
Can it Be Preventedor Managed?
Yes! Regularexercise focusing on strength, balance, and flexibility can help
delay thedecline in stair-climbing ability. Activities like walking, strength
training,yoga, or Tai Chi can maintain or improve mobility and make stair
climbingeasier as we age.
If someone isstruggling with stairs, it's important to consult a doctor to
check forunderlying health conditions that may be contributing, such as
arthritis orheart disease.
Q5 Whatare the predators of an ostrich?
KR Not exactly sir. The observations of the forest conservation
materialsay a little different story<
Ostriches,being large and fast-running birds, have few natural
predators, but they are not entirely freefrom threats. While adult ostriches
have few enemies due to their size andstrength, their eggs, chicks, and even
sometimes adult ostriches can fall preyto a few predators. Here's a rundown of
the main threats to ostriches:
1. Predators of Ostrich Eggs and Chicks:
Hyenas: Hyenas are opportunistic scavengers and can targetostrich nests. They
will often eat ostrich eggs and, if the opportunity arises,will go after chicks.
Jackals: In Africa, jackals are known to dig up ostricheggs. They are smart and
persistent, so they are a notable threat to the eggs,which are left in nests on
the ground.
Lions: While lions typically hunt larger prey, they maytake the opportunity to
eat ostrich eggs if they find a nest, especially inregions where other prey may
be scarce.
Cheetahs: Cheetahs, known for their speed, can huntostrich chicks, which are
more vulnerable when young and still developing theirability to run fast.
Vultures and Birds of Prey: Large birds like eagles orvultures may target
ostrich chicks. These birds are skilled hunters, especiallywhen the chicks are
young and small.
2. Predators ofAdult Ostriches:
Lions: Though adultostriches are strong and fast, lions can sometimes pose a
threat,particularly when an ostrich is sick or injured and cannot escape. Lions
canambush or attack in groups.
Crocodiles: In areas where ostricheslive near rivers or water sources,
crocodiles may attack adults, especially ifan ostrich is wading in water and
can't run away quickly enough.
Wild Dogs (African Wild Dogs): Packsof wild dogs can sometimes take down an
ostrich, especially if the bird isdistracted or weak. Wild dogs use teamwork to
wear down their prey.
Defensive Strategies of Ostriches:
Ostriches are incredibly strong and capable ofdefending themselves. They use
their long, powerful legs to deliver lethalkicks if threatened. In fact,
ostriches can kick with enough force to kill alion or a human if it comes to
that. They also run at impressive speeds (up to45 miles per hour) and rely on
their ability to escape threats through speedand agility.
So, while adult ostriches are not easy prey for mostpredators, their eggs and
chicks are much more vulnerable
