I've kept up with the Isle of Man for about 15 yrs now. I used to love to watch Joey Dunlap teach the young kids a leson on that track {and others}. The guy was at least in his late forties, maybe early fifties when he finally died in a race {not the Ise of Man but another TT race}. It was great to see this guy lap a second or so faster than everyone else, win, get off the bike, take his helmet off and the feller was a grey as my grand father {as grey as I am now!}.
If you only watch one bike race on TV,,,, watch the Isle of Man. Nothing like watching a bike become airborn on a public road at something like 120mph!
