There is 0% chance that H 2 O 2 in your ear will have any actual effect on a cold or flu. (Not unless magic really works.) I stopped saying things like this (i.e., 0% chance) years ago when I took a stance on trans vs cis unsaturated fats. My stance was "How the hell could flipping a bond arou...

Pilot whales are social creatures; may it be that elderly females (past child-bearing years, assuming they live past that age) within a pod could adopt orphans?

Re: Pilot whales

Most of deaths in the population will take place in early life (I'd guess first 5 years). This will result in two things.
