Hi, I took my PPL in January last year in the U.K. aged 58.
To be frank after bringing up two kids and putting them both through university it was really the first time in my life that I could afford it.
My licence is my proudest possesion and Im so glad that I didn't let my age put me off. I also live in Spain, near Malaga, but am considering going to Florida in the near future to do an IMC and some hour building. The costs in the U.K. are very high especially when youn factor in landing fees. I must say that nI have also looked at flyinspain aat Jerez but I just dont think anyone can beat the U.S.A. prices.
Anyway, go for it and good luck. Age is only a number. Mind I wish I had your number again.
