Need to get out more

I placed a bet with 365 on an outsider at Cheltenham and, as the oddschecker page refreshed a minute later, it showed the price had moved in from 28 to 22-1. I'm sure this was down to lots of other bets over a longer period of time, but the seemingly instant price cut could, in the mind of someone who needs to get out more, been in reaction to my bet. Such is my life.
