[Spider-Man] What would happen if the Vulture tried to steal the youth of Benjamin Button?

The Vulture sees a 20-year-old-looking man walking down the street. He tries to steal his youth. The man turns out to be 60-year-old Benjamin Button. What happens to both of them?

Either two(of maybe half a dozen) possibilities may happen:

1. The Vulture steals Ben's youth, forcing back into an old man. Vulture becomes younger, Ben older. Ben will continue to reverse age from what ever age he biologically becomes. They could effectively become immortal if every half century they swap ages.

2. The Vulture steals Ben's age, but because of the way Ben's age is reversed the Vulture instead becomes *older* while Ben becomes younger. Ben's condition is so absolute it causes anyone to try and change it to feel the effects also. After stealing the age the Vulture will age as normal(probably not for long since he is suddenly an 80 year old man) and Ben is a dead fetus.

Those are the two most likely scenarios that could happen. Unlikely ones are:

1. Vulture steals age. In stealing age **HE** becomes cursed with reverse aging and becomes an 80 year old senior citizen. Ben is cured and will age normally if he somehow doesn't turn into a fetus. Vulture will eventually have to find a way to avoid de-ageing into fetus; maybe something similar to scenario 2.

2. Vulture steals age. Ben ages into a fetus, Vulture ages younger. Vulture is now cursed with the same affliction that Ben was born with. Now instead of making people older he makes them *younger* to stave off turning into a baby.

3. Nothing happens. Ben is completely immune to the effects of age tampering and will de-age ceaselessly until he dies. Vulture gains nothing.

Unfortunately with Mr. Button dead in his universe we have no way of studying how his condition came to be or works. Maybe it was the clock like the Universe Viewer showed, but probably not. Unless you have a time machine or an alternate universe version of Mr. Button that we could study all we can do is guess at how his aging works.
