My latest thought...can Dares be seasonal?
Working in a sector that analyses retail sales this is a concept all too familiar, people buy more chocolate at Christmas, more lager in the summer, Easter eggs at Easter and so on...
But does this apply to Dares also?
Do you tend to have more people doing risky public dares in the summer with the better weather?
Temperature I'm sure must be a factor...I'm sure very few people would try skinny dipping when...
