By the time I got home some four hours later, I felt really drained of energy. And my pedometer registering 18,365 steps only told part of the story since the great bulk of the steps I took today were on stairs leading uphill -- first to 424-meter-high Siu Ma Shan and then 435-meter-high Mount Butler. Also, after getting to the top of Mount Butler, there came a nervy descent down the Jacob's Ladder on Hong Kong Island that I think is quite a bit steeper than the section of trail bearing the same name over on the Sai Kung Peninsula -- and potentially more slippery than usual this afternoon because its steps were on the wet side and covered with lots of fallen leaves.
