i complete 1/2 the errands 
was walking ok, but once i got near the flat where i was
supposed to pass the CD+DVD, the muscle pull started to set in
then after i gave the items, i told myself i can't complete
errand number 2, which is to park my bike on main stand.
would it help if i took a shower to cool the muscles?
you should buy a can of those spray thingys for sore muscles
