Yeah, do it. I’ve no experience of roped climbing but got into bouldering around Easter time after my youngest showed an interest.
As others have said, it’s great fun and as social as you want to make it. I’ll go with my daughter or friends some sessions, on my own at other times. I am quite lucky though as my local climbing wall is really decent with regular resets of problems which keeps it interesting.
I found it took a couple of months for my hands to get used to it though, it puts a massive strain on your finger tendons if you’re not used to it and it can take quite a few days to recover.
Be warned though, as you start to improve it can get pretty addictive, And as for the age thing, I’m 43 and haven’t found that a hinderence.
