Letter from my GP. Two pages long. He talks about Sir Bradley Wiggins' power output and tells me that cheetahs must run at 70 mph in order to ovulate and that these turns of speed indicate they are hunting and that there is therefore food for all the family.
I have no clue what triggered this, except he says that exercise will reduce my risk of mortality by 10% (which I doubt).
I think he may have gone nuts!!
