I'm glad you went anyway. The first time I went I had a migraine, but there was no way I was missing out after looking forward to it for so long.
I agree with the mental side too. When I climb I can switch off from the stresses outside and just focus on what I'm doing. At least most of the time I can. Sometimes anxiety carries over to the wall with me.
I was literally just thinking about how our grandparent's generation was living to their 80s and up yet our parent's generation seem to be dying younger. It was going through my mind what had changed and high levels of medication was one of my thoughts. Also vaccination wasn't at the same levels in our grandparent's generation.
