In today's badminton game, Aaron won his first game of the fall season! Aaron had his shirt off and it seems that some underarm grease on the shuttlecock was a positive brainwave for Aaron. He also tried rubbing it on his head to similar good effect.
I challenged him to a rematch and I won by 3 points. Aaron said he blacked out a couple of times in his effort to beat me.
I hope that the weather holds up for more similar challenges!
Here is a picture of what Aaron looked like playing with his shirt off.
