Having spent six months running a couple of miles three times a week, and then stopping in February due to recurrent knee, thigh and hip pains (too much weight in the middle!), I have finally re-converged to slobdom. It feels bad.
I have therefore determined to buy a bike, and do 30 minutes of serious biking three times a week as a non-impact aerobic thing. I am inspired (only a small amount) by 'Le Tour' of which Clare is an avid fan. Round to the bike shop, then, on Saturday.
Reading 'Not Even Wrong' one is struck by the sheer, sustained brilliance of Ed Witten. This puts whatever intellectual pretensions one might have completely in their place. And that's from a distance - whatever must it be like for his close colleagues?
