A little over a year ago I began training to swim the English Channel this September.I will be 58 years old then.My friend thought I had lost my mind; my wife, though not fearful for my sanity, was somewhat apprehensive.The question I was asked over and over was this: why?A challenge and an element of adventure are welcome whether you are 20 or 58.But why did I decide to swim the Channel at 58?The Channel has always been the supreme challenge to swimmers;a test of ability, endurance, luck and even bravery.It is this challenge that appeals to about 100 swimmer a year who are willing to spend time, effort and money to try it.One fact that contributes to my interest is that, if I succeed, I will be the oldest person ever to swim the Channel.I don't think I'm a superman.I do think I have at least three things going for me: First, I am training hard.Second, I am a very goal-oriented person for whom this swim has long been a goal.Third, I have a feeling I will be psychologically ready.
