Healthcarefag here- do alot of IVs and I'm always looking at people's veins, at work, at the supermarket, all over. Vincent Fusca has some nice hand veins. Should be easy to put a line in. The thing about veins is that they are like a fingerprint- they may become more or less prominent with age, weight, hydration- but their pattern is unique to you and they really don't change location. Even your left & right hands are not mirror images of one another.

I submit to you anons pics of JFK Jr's right hand alongside one of Fusca's. I am not sure what to think. Fusca has a prominent vein that crosses from pinky area over to middle finger area. I could convince myself that I see it in one of Jr's pics. Who knows.

One clear difference seems to be that Jr's hands were hairier than Fusca's. You can lose your hair, but you really can't change where your veins are.

Maybe some other anons can find clearer pics for side-by-sides?
