Ice scream

The day after Christmas Day (Boxing Day), a bunch of raving lunatics plunge into the lake called The Serpentine in the heart of London's Hyde Park, for a swim in the freezing waters. Sheer, eccentric, madness.
Which therefore doesn't explain why, at 1.30 this afternoon, my daughter and I plunged into the freezing waters of the swimming pool at The American Club in Tokyo for what they aptly call the Polar Bear swim. Four hours later, I'm beginning to defrost.
