Oh neat....

Those spending 8 hours 45 minutes or more in the saddle were six times more likely than average to receive such a diagnosis.
But researchers said that the findings, while surprising, did not necessarily mean there was a direct link between cycling and the disease.
One possibility is that cyclists are more aware of their health than the average person, meaning there is an increased chance of diagnosis, although they said that bike riders were no more likely to visit their doctor than average.
Another explanation however is that cycling does place more pressure on the prostate, although further research would be needed to establish whether there is definitely a link.
Dr Mark Hamer, of UCL’s School of Epidemiology, said: “It’s tricky to interpret. Obviously the men who are cycling for the most amount of time are more health aware so they may be just more likely to be diagnosed.
“Or there could be a genuine biological link between trauma in the area of the prostate associated with bike riding.
“We were quite surprised by the size of the finding for prostate cancer so it does warrant further investigation, but we can’t draw any conclusions from this study
