We learn our motor skills while young (how to walk, how to catch a thrown ball or hit it with a bat etc.... how to hunt when we lived in caves) and the human body has evolved to do that.
I think you may have answered your own question in the above paragraph - Surely you will use those same motor skills already learnt during your younger life to also fly an aeroplane - Or else there will be this horrible dreaded cut-off line in life where you are not allowed to learn anything new after a certain age.
Granted though - as you get older reflexes may get a little slower but this is for the individual / medical check to assess.
Just my opinion.
