hahaha ... guess is too late to worry about anything... Frankly, we should all just enjoy it. Dun think so much about it. As long as we work all together.. things should work out fine.
For OBS, if i'm not wrong.. is not so much of a physical challenge, but more of a mental one. You dun need to be super fit to go thru all of it.
So Cheers!!We'll all stick together and hang it dry! LOL
