I think the scenario would be different in the UK, I can’t speak for London, well, I don’t know if I can speak for today either, but when I was a kid, I was MADE to give my seat up for old people. Back in MY DAY, I tell ya!

Take it from someone who learned how to do his high school homework on the subway, to avoid the unthinkable of giving up a seat, you must learn the Zen Of The Subway Seat: Let all outside the Self fade away except for the perception of the envirionment necessary for self-preservation, the residual awareness the dozing gazelle maintains to avoid the leap of the lion.
