I have climbed with many women who learned to climb in their forties or fifties and could rip it up. Essentially, climbing is like other sports- you get out of it what you put in.

If you go into a situation saying it's not worth it unless you can perform at a certain level (whatever level you ascertain as good enough), then you are setting yourself up for frustration. Just go out, try it, and if you like it do it more.
