My bum is numb, i sat on the stupid small stool for hours using the laptop, Suddenly, when i stood up, i could not feel my bum ! It was the leg numb feeling but on the bum. Couldn't walk, so i laid on the bed and asked for advice. I was told to jiggle my bum, i tried. But not effective, so i rubbed my own bum and i'm feeling better now. Oh ya, the MRT i took today, jammed its brake three times in the middle of nowhere and one poor lady fell 2 out of 3 times. She was so pissed, she sat on the floor till we reached the next station.
