I think you might be a superhero.It's not that weird, but it seemed to me that this is a funny feature of my body.
I never have a hangover. In general, never in my life, all my peers suffer after parties, they cannot get up in the morning, they feel so bad. And I don't feel any difference at all with any other morning. I suppose that this is due to the fact that in my body alcohol is processed very quickly, intoxication occurs instantly, but sobriety also comes very quickly.
Silver never turns black on my body. Some of my friends periodically clean their jewelry as it turns black. I somehow colored the silver ring with a chemical reagent to make it completely black. After a week of contact with my skin, the ring began to shine.
