Well, kids, lemme tell you something. As you know I'm 70 now and my lovely wife Ann is 69, though I've been skiing since I was a kid myself, Ann didn't start until the ripe old age of 23.
My secret is that I keep refining my technique and smoothness in skiing, almost automatically, I just ski with whatever takes less effort, no superflous movements. In skiing very smooth you fight nothing on the mountain, rather you look at what conditions and terrain can do for you.
Steep stuff is easier to ski because gravity helps you, ice is solid underfoot and won't give, so the edges hold well, crud and slush allow you to take a straighter line downhill, etc.
Just the last couple of years I felt my strength waning, so I try to stay waway from situations where I have to manhandle my skis, bumps, deep powder and trees, mainly.
The biggest reason many older people give up skiing or just make a few trips a year, and I have former instructor friends who ski rarely, is that for old people it is getting too much of a hassle.
Even if you live within an hours drive of your home mountain, getting dressed in all that regalia, lloading the equipment, driving and finding a praking place close enough so the carrying of the equipment doesn't exhaust you, putting on the boots, and last but not least, standing in a long lift line. And then the reverse of all that at the end of the day.
I never thought I would feel that way, but I'm fighting it, successfully so far, but foregoing a luncheon with friends or a card game or playing with my grandson who is two-and-a-half and will be introduced to skiing by us next season, is hard.
I'm hoping that my grandson's introduction of skiing will give us renewed reasons to keep on, but after 56 years of skiing I can't think of a reason why I should make even one more turn. Well one, I like it a lot.
