I returned to cycling after a gap of 30 years and found that I enjoyed it in much the same way I did as a youngster. I now ride mtbs, which I never did before, and the fun of taking that detour trail, or the muddy bit, or the path along the coast often just makes me smile as I ride. ( I've even been known to sing out loud as I ride
)
The falling off isn't as much fun though.
