Wyr Have the ability to eat anything without it having an effect on your body or have the power to be bullet proof?

eating ability: your body will have the ideal fat % all the time, you can eat as much food, you will never get fat or sick. you can even eat nuclear waste or poison nothing would happen. but that also means alcohol can't make you drunk, drugs can't make you high and eating protein won't give you more muscle etc.
bullet proof: you are bullet proof, knife proof, proof from small to medium explosions and car proof. the only downside is you can't swim because you sink in water.
which ability would you pick, why and what would you do with it?
