Just noticed this thread (nothing gets past me). I don't intend to stop gigging any time soon and I'm not exactly in my teens myself. Basically, I can't not do it.
I know how you feel but, after breaking my back, I simply can't do it any more. So my playing career (that started when the date started 197..) had to end on the live front.
I'm in Somerset and still try to keep as involved as I can (tricky in a wheelchair).
Keep it live brother as long as you can stand up. There's always younger people to carry your amplifier!!
Take care
Paul
