Nah.... just did interval training last Saturday.
Then again, I did sleep past 2 am last night.... lotsa work to
do.
Maybe I'm just a little zonked-out, that's all.
Yeah... cause muscle aches can often masquerade as 'chest
pain'. I know this because a few nursing colleagues and I
started panicking once cause we had 'chest pains' that kinda
restricted our breathing and prevented full inhalation. We
thought it was some kinda cardiac issue. 
But heng ah... it was just muscle aches
from all the lifting and positioning of heavy patients we had to
do.
