I just never subscribed to the theory that at age 55, you fall off the face of the earth on the Tour. I always felt that was too young of an age for that.
I would sort out all the arguments and see which belonged to fear and which to creativeness. Other things being equal, I would make the decision which had the larger number of creative reasons on its side.
I think that maybe that's my weakness, in that I don't know how to do it, so I just do what I do and try to do it as passionately and as well as I can.
