In the military they teach you to use the first aid gear that was carried by the person you are helping, that way when you get hurt later, you still have your own first aid gear for the person that is helping you to use. I would never give my one and only spare tube to someone, but all my friends already have a spare tube. Except two of them, they have switched to tubeless, if they needed a tube they would use their phone instead to call for a ride home.
Bike touring, I carry two spare tubes because on rare occasions you can have a catastrophic failure that will make a tube un-patchable. But for my rides near home, only carry one. But I carry some self adhesive patches for those times that you can't find what it was inside the tire that re-punctured your tube.
About a year ago, this thread was started on the touring forum on what to carry as an ID in case you got hurt.
What to put on ID tag?
After reading comments on that thread, I got some small plates made with my info that I put on my watch band. If I am found on the side of the road unconscious, that has my name, birthdate, and in case of emergency phone number.
