People are frequently heard to say "this or that is an acquired taste." This has always seemed an odd thing to me. For starters, if there isn't a taste for something to begin with, why do people keep eating/doing that thing over and over? Is the brain going to suddenly realize "Hey! I was wrong about this stuff, it's actually pretty good?"
NO! It's called acclimation. You're not conditioning yourself to like it, you conditioning your body to tolerate it. What kinds of things are out there to prove this fact? Poisons, for one thing.
What else can you condition your body to tolerate, despite the simple fact that it is nothing but pain and misery?
Yeah, that's right, exercise is just another poison waiting to kill us all. People say it's good for you, but every time I do it, I end up sick and in pain for a week. Kinda like a poison.
FYI, I just biked for five minutes and I'm ready to die.
