I'll become vegan, for the environment (lmfao like a speck of dust like a single human being could cause enviromental hazards for consuming meat) and for my health
/dies from cancer before middle-age.
There's a fuckton of variables. It's like saying, what if I increase the aggressiveness of the police cars code? Well, that's how GTA happened. Same with diet, what might work for you won't work for someone else. For example, milk on early morning (even lactose-free milk) can cause unpleasantness for me. It's simple, don't consume milk until i've been awake for at least an hour or so. Let my system settle.
