Really? I love having friends who are into totally different things than me so I can hear about those things. That includes people in their 90s. A couple of people in wheelchairs. For me, that's the richness of other people--that they bring things to the table that I don't.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
