yesterday I learnt sth fr my sis
i got backahe
so i askeed her if she got any magic to help me
she made me do some back exercise
she said when your muscles are stressed
means the blood vessels there are constricted
so not enough oxygen
so there is acid accumulated there
so you must do the contract and relax cotract and relax
exercise
this improves circulation and brings blood and oxygen to the
muscles
and i ask why sleep also can be ok
she say when u sleep musles are relax so more blood circulation and
more oxygen lor
heehee so happy
