Darn. Good thing I didn't read this thread until after I got back from diving the pants off of folks half my age this week. . . probably not supposed to water ski either - hope I don't see that article until after I get back from water skiing with my family this summer.
One of the nice things about being over 50 is that our memory starts to fail, so we can conveniently forget that we read this post and that we're not supposed to dive after 50, and keep on diving.
