When did you last do something for nothing in return?
I don’t know that I ever do.
I consciously choose to do many things that have no immediate or short term return for me, yet I do them to create a social environment that will offer me the greatest long term probability of survival.
I do “pay it forward” often.
I pick up hitch hikers, I help out at many different charities, I do many acts designed to improve the function of society to deliver more choice and more security to more people – with the objective of making that all inclusive.
So on the very longest of term outlooks – many tens or hundreds of years, I intend to get some benefit from these actions, so they are not entirely without benefit, and not too many people expect to live for thousands of years, and I think there is a small and growing probability that I might.
