hello !

I'm very impressed with the YawYan art.
I'm very interested to study it.
My concern is this:
I'm a callcenter agent working 11pm to 8am. Do you think it's still ok
for me to enroll in a physically demanding activity?
if so, which is the better session beforework (7-9pm) or
afterwork(9-11am) ?
what will be it's effects?

pls advice ...
especially if you know someone who has the same situation.


ye
