Ahh really cool Pietro, so I see you have done some climbing before, awesome. I am now walking around and convincing all my friends to come and try, many already tried and really enjoyed it.
I noticed quite a big percentage of people have strong fear of heights so just by facing this fear in climbing is a big step, plus all other gifts as mentioned in the blog.
So good luck on your first climb after such a long gap, perhaps you could do some reporting, i am very curious to know how your level has changed in those years
