comment Is the sun's damage to skin sufficient to warrant protection anytime the average person goes outside or just for extended periods?
Probably as important, the incidence of skin cancer is up over the past 30 years because of 1) the idea that getting a tan is healthy 2) the intensity of sunlight hitting the earth's surface is going up. An increase in melanoma has been documented. who.int/uv/faq/skincancer/en/index1.html skincancer.org/skin-cancer-information/skin-cancer-facts

comment Is the sun's damage to skin sufficient to warrant protection anytime the average person goes outside or just for extended periods?
There are dermatologists who advocate for never exposing the skin to direct sunlight. The interview I saw had terrific looking skin. The increase of UV content of sunlight over the past few decades makes this seem like a better idea now than previously. Clothing, hats, gloves and parasols may be recommended in these cases because of the chemicals in sunblock.

comment Why do people die?
the question, called senescence is kind of an open one in evolutionary biology. There are some organisms which appear not to die - dividing amoeba and perhaps the microorganisms called hydrae.

comment Why can't humans drink sea water?
@Sz. its true - most salt water organisms have osmotic control I think - even mammals eating salt water fish probably have adaptations for all that salt. I don't doubt that human beings could also have those adaptations, but they just dont at this point.

comment What is variation in Speciation
you should probably go to reddit with this question - they are more focused on handling such questions and dealing with the interface of the general public with science there.

comment Why we have no enzyme to digest cellulose?
there's lots of shades of meaning here, which is definitely interesting to talk about. Organisms are so optimal for selected traits that they amaze and astound us - better than we can design ourselves in many cases. Where selection has not had as much pressure (e.g. long life, resistance to damage and disease, empathy, speed, intelligence) it can seem that they are strangely vulnerable.

comment Where’s the flaw in my proposed TB Treatment?
also in tubeculosis, the mycobacteria go into tubecules and can remain in a dormant state for prolonged periods of time. Its unlikely this will kill those protected and dormant bugs.
