I've always wondered, if we evolved from earth over millions of years, why can't we stay exposed to direct sunlight without severe SKIN and EYE damage? I'm not aware of any other
earthly species that has a Sun exposure issue (SKIN CANCER)

I love that soap. But I won't eat it. Though there is a popular professional trekker/adventurist who brushes his teeth with it. No kidding, brushes his damn teeth with Dr. Bronner's soap. Hmmm, I might just try that.

I like it for use while camping/backpacking. It's highly concentrated so you don't need to bring a big bottle. It's good for washing yourself and for washing dishes. And the peppermint scent helps keep some bugs off you.

(While it says it can be used for brushing your teeth, I've never done so.)

Every living creature from Archaea to Bacteria to Plants to Fish to Mammals can die when exposed to sufficient UV-radiation, let alone simple cellular damage in Eukaryotes.
All cancer is genetically based and a cancer call is referred to as an immortal cell, one whose apoptosis pathways are no longer functioning. UV-radiation can cause sufficient mutations when produced at the right wavelength(s) + exposure time(s) allowing for mutagenic effect, whether in plants or animals, potentially disrupting apoptosis.

104, we are interesting animals in many ways. We have unique features in our DNA, which get very hard to explain, mammalian dive response, can outlast any animal, and seem to require a mean air temp of 72.

I’m not sure there are other endurance predators.

Dogs. Notably evident in the stereotypical "hound" hunting method, steadily pursuing and harassing prey at relatively low speeds for extended periods until the prey is exhausted.

Spotted Hyenas also utilize this method. (Although they look similar to dogs, they're actually biologically closer to cats. They have just evolved similar body structures to dogs because they utilize a similar persistence hunting method like dogs, as opposed to the high-speed pursuit hunting or patient ambush hunting of true felines.)

I thought drunk posting was frowned upon

Well....I was cleaning it once and it went off. Don't know if that counts.
