I seriously doubt that a good pilot is made of fast reflexes and motoric skills.
Its more ......
the reaction times
the ability to cope with the workload
the ability to understand, correctly read back and swiftly react to what you're being told on the radio without asking the controller to repeat each time
etc.
I would say more, but I won't in public as I've been in the right hand seat of aircraft of a couple of over 70's in the last year or so whose abilities to cope on their own have somewhat worried me (and I unfortunately was not acting in capacity of instructor or examiner !). I fear they may be PPRuNe readers and hence do not want to embarrass them in public.
It's important not to kid yourself that its easy. Remember that unlike driving, or sailing you can't just stop on a whim.... once you've left the tarmac it's up to you to get yourself back in one piece, nobody can do it for you. So great if you want to do it, but perhaps at the very least consider a suitably qualified safety pilot.
