Why am I naturally a pro?

I’ve drank a few times in highschool but never got really into it considering I was doing way harder things at the time.

I started drinking as an adult a little bit this month

For some reason no matter who it is I’ll out drink them and wake up the next day feeling fine. Do I get drunk? Yes Does my stomach ever hurt? Yes.

But I never ever throw up, get to wasted, or get hungover no matter how much I drink
