pei fu. i nv do vertical challenge before. to me climbing stairs sounds like crazy people do. but then when i do, i seem to enjoy poking at people's corridor, see what they plant, see who smoke, see what furniture they display outside, see the cctv brand they useBro, thanks for your reply.
I scare knee cap broken or give way.
Thks for the confirmation.
Cos I am gonna train for vertical challenge n I wanted to know ok to sign up or not.
I am not young anymore.
Lau kork kork.

when i look at dawson, my ball shrink, dont dare to climb. i only do some point blocks climbing, take lift go down. and do afew times once awhile only.
trick is to keep changing block so u dont see the same thing all over again
