What an argument.

Sun: can I live forever in a cave so I don't get any sunlight? No, you can't (in practical terms). But you can use sunscreen and you can limit the number of hours you get exposed to sun (don't be a dick and lay down on the beach 5h straight during hot summer days). Problem fixed.

Alcohol: can I live forever without drinking any alcohol. Yes, you can. Problem fixed.
