Maybe you missed the part of my post where I said "I've got lots of things to do", and that I'm not complaining about my situation?
I have tried nothing to replace concerts, because concerts cannot be replaced. It's like suggesting you replace your beloved dead relative with another person and learning to enjoy them more than you did your dead relative. That's my point here, about the only things I enjoy about as much as a good concert are sex and LSD (although a nice mountain hike gets pretty close, and yes, I've been doing that). To blithely suggest "learn to enjoy something else MORE than concerts" may imply that perhaps you have a different relationship with concerts, so you fundamentally don't understand.
