Look at Armin van Buuren, Darude, Jean Michel Jarre etc. For some reason there are many music producers/DJs in their 30s-60s that look way younger than they should ;-) I don't remember who was that but one DJ that was ~42 looked like 18 (non-asian) and everybody was freaking out (I'll try to find that pic somewhere). Maybe this type of music energy activates something in the brain, who knows?
