Great answers. Thanks all.
I'm a little concerned about how I'll be mentally getting back on the slopes in March after my injury. Being an intermediate and 53 years old, I really wanted to push myself this season. But the fractured humerus derailed that. Although the collision had nothing to do with my skiing as the other person ran into me, the fall and it's consequences are definitely remembered. However, right now, sitting in my office, I'm chomping at the bit to get back on the slopes.
Do you get to an age/ability where you just decide that you have fun at the level you are and don't take the chances that it would require to improve one's ability? In other words, how do you know where your personal risk/reward line is? I'm thinking that's a personal decision that each of us have to make.
I'm about your age, and have experienced injuries and health scares over the years, although nothing major from skiing. I'm still motivated to improve, as I enjoy both the thrill of skiing and the challenge of gaining more mastery over the skills. To date, I haven't backed off much in taking risks -- I was uncomfortable with large drop-ins 25 years ago and remain so now -- but I think I've gotten better at judging the skills needed to successfully ski certain conditions and honestly assessing whether I'm able to do so. And I'm probably more willing to build skills now than I was when I was younger, which allows me to add to the challenge over time.
Good luck in your recovery -- my best advice is to get back on the horse and ski once you are cleared medically. I'm sure you'll think about the injury for awhile, but over time the fear of reinjury will lessen.
