U may1 or may2 ?? hehehe waist band ?? i do wear it but it is useless for me as i don't sweat. it is for ppl whose palm can sweat like mad. my friend. samuel 's palm sweat like a running tap uses a wrist band and i uses head band to hold back my hair.
i know chen hong wore one in the all england semi final cos i saw him take it off when he beat roslin.i do not know how good it is but my dad says it helps wen you are tired. it promotes good posture
hahahahahaha, he will really need help attracting gfs then. or maybe he's growing old and wants to keep his back straight????
