Activities Outside School

I do basketball outside school every saturday and sunday.I spend 1hour on basketball.My father is the president of filipino assosation of singapore so i could ask if i could use a ball to play.Basketball is nessasary because it keeps u fit.It does not efect my studies because every friday i would study.I do not feel stress because after i finish my studies i could do what i want at the rest of the day.I think pupils should be involved in activities outside school to be fit.
