Gym has this machine that simulates
climb stairs...... tried before and it seems to put quite alot of
stress on the muscles , after that quite tiring ,rather
shiok.
I remember being stuck in the lift while I was very young. Those
days the lifts stops only on selected floors unlike new buildings
nowadays stop at every level. Someone tried to force open the lift
and all we saw was a orange sunbaked brick wall.
