I learned at 57 and have not looked back since. I use a upper body protection from Demon and highly recommend that type of armor.
But, the number one thing I would recommend is a good instructor 'day-1'. I used a very experienced guy at Beaver Creek and he started me out very slow. Yes, I still had some falls but knew when to call it quits for the day.
Now, 2 years later, I go to Colorado twice during the winter and the instructor has become a great friend.
Best of luck -
