Give aerobatics a go if you have not already before. After flying aeros you come down feeling on top of the world and like you can conquer anything (well that's how it made me feel) and age isn't a factor as I know a 72 year old instructor that still spins and loops. Also you could get as many types in your logbook as possible before the time comes that you hang up your boots i.e. 172 TB10 HR200 M20 etc.
and one last thing - [URL="www.highlandaviation.com"] I imagine this will change your feelings about problem - give it a go, if only once
