Standing Room Only

At what point does one become less able to stand? I was considering this on the 94 bus on the way home, sitting in the seats reserved for those less able to stand. I am not in peak physical condition owing to the recent surgery, but I'm not exactly a snivelling mess who can't be let out of the house alone. Public transport is still something of a mission, however, as I still have iffy eyesight and tend to walk into seats/walls/Albanians when alighting public transport vehicles.

Well, fate dealt me a blow earlier as I was pondering this question whilst trundling along the Goldhawk Road aboard the 94. As I was smugly cozying up in the said less able seats a partially sighted gentlemen got on the bus and sat next to me in the seats of the people who are less able to stand, thereby pinning me most uncomfortably against the window. He then proceeded to eat very slowly and noisily (and being partially sighted, not very accurately) what appeared to be a battered sausage and a portion of greasy chips from a paper bag whose scent and grease insulating properties can only be described as woefully inadequate. There you go. Karma. I'm taking it as a sign that I am perfectly able to stand.
