I was suffering smiles whilst cycling recently from both sexes, and I was a bit worried about the blokes, but they've stopped that now. I think it was a means of keeping their face warm during the winter. And now it's just females from age 4 - infinity. Serious, when I go past a local graveyard I see the tombstones wobbling. Does noone else really not get cute natural smiles from about 70% of girls whilst cycling, but never when stationary?
