i was fine for 5-10 min at first when i started playing badminton with my friend. then im done since i need to go back home. while on my way back when im on my bike i feel suddenly sweaty. i found a shop and buy a drink.

im suddenly sweaty and panting when im paying for my drink. i rested on my my bike while waiting my sweat to evaporate while drinking. look like i need to stretch first before playing. not it a problem before. look like im aging
