Gotta hand it to this man. Seems like the sort of dude who probably actually lived during his life, meaning that there's a decent chance he looks a bit older than he actually is. My guess would be early 60's, but wouldn't be surprised if he ended up being closer to the half century mark.
Anyhow, Old Bro Medicine Show looks like he's still got it. That fingerflip trick is pretty dope regardless of age.
