Hi Leon & welcome.
As a point of interest are you going for the full JAA PPL or the NPPL?
I am 67 yrs old & I started last July on the NPPL because at my age a career in aviation is not there! Also I just want to enjoy boring holes in the sky in daylight. The medical requirements for the NPPL are DVLC driving type, self certificated, signed by your GP. Total hours reqd are less at 32, Flying limitations are at the moment restricted to UK airspace only. Depends what you want to do after you qualify I suppose.
Good luck
Trevor
