More willpower required

We were hopeless at badminton last night. We started by messing around playing left-handed (one of us had an injured right hand and the rest tried it out of solidarity) and using a shuttlecock with half the feathers broken. Embarrassingly, we weren't noticeably better when playing right-handed with a new shuttlecock. So we gave up early and went to my flat to drink tea and eat chocolate. I'm not going to get any fitter like this...
