YouTube can't solve all of our problems

 My family and I have had a very interesting conversation today about YouTube. 

Yes, I understand that all sorts of things can be learnt from it but you can't learn how to drive a car or do heart surgery on it. Yes, there might be some professionals on there but that doesn't mean that you can just hop into an operating room and cut open someone's chest cavity. You need to go to medical school and get training. 

Anyway, how we managed to get to that discussion was that Blue Spider in Guildford has a new policy where if you want to go on the bouldering wall you have to look at a picture and tell an instructor what the people in the picture are doing wrong. After that you are free to climb. You aren't told how to climb safely, but as long as you can spot the difference between good climbing and bad climbing, you're all good? That's super messed up if you ask me.
