Have they "gone under the knife"? I´m talking plastic surgery.

I mean they look so young and are in their mid fourties. And also all of them have great hair (Richie looks a bit like a woman, sorry!). I mean how come all of them look so young AND have great hair? Can we be honest here? I mean it doesn´t really bring down the love I feel for the group, but I just wanna know... U know?
