Go for it
I recently returned to gliding at st Remy de provence after a break of five years so that I could fly my grandkids
Twenty plus years ago it was a saviour after I lost my class one medical. It is far more demanding than flying powered aircraft - more like three dimensional chess.
Gliders aren't easy to fly initially but are very rewarding.
I went through driving the winch, trail lessons, instructor, mountain flying and aerobatics.
I stopped because of bullying at a local club..its not always easy as like all clubs there are politics but if you get the right club you will enjoy it.
Most clubs you need to arrive and get the gliders out..only leave when everything is put away.
St remy is a training field so they have a morning and an afternoon. Group which suits me as I'm getting old in the tooth.
I paraglide mostly as I can go when I want if the weather is right...not that often...and I can leave home have an hours flying and be back home within two hours but it involves far more risk.
Read as much as you can..most clubs have libraries of sailplane and gliding.
Remember the old guys who give their time were once young.
