I agree with the advice to take a lesson and rent skis to try it out.
DH learned to ski at 49, 12 years ago, and loves it. He did take a class, though. The ski schools around here segregate the adult beginners from the kids and there is support in the group. After the lesson everyone would compare notes on different trails and offer encouragement. It was a bonding experience.
I had skied as a teen and took it up again at 45. After a couple lessons I liked it more than when I was younger.
We do restrict ourselves to the green and blue trails (the easier ones). It's still a lot of fun and great exercise and there aren't as many speed demons to watch out for.
Try it! You'll probably have a great time.
