I took up hang-gliding when I was 48, packed it in at 62 and it was the biggest kick I've ever had in my life, going cross country silently no noisy motors, wounderful.
canoeing/scuba/potholing and many other sports naah------------ but doing this beat the a+s off all things I've done, plus a lot safer than paragliding as well, been flying the Pyrenees down here as well as all over the UK, loved it, now too old now for that sort of thing but as I've since said now looking at my phantom videos I'm still getting a similar kick without the risk at my age.
