Mother Nature doesn’t care if you’re having fun.
You will not be stopped! There are things you can’t do because you burn sugar with oxygen, or your bones aren’t strong enough, or you’re a mammal, or human. Funny chemicals may kill you slow or quick, or ruin your brain … or prolong your life. You can’t fly like an eagle, nor yet like Daedalus, but you can fly. You’re the only earthly life-form that can even begin to deal with jet lag. You can cheat. Nature doesn’t care, but don’t get caught.
