Icy

It's all relative. My personal trainer was ill tonight, so I decided to go for a swim. The life guard was huddled up in the corner with as many of the clothes he could put on. He said the pool was heated. After jumping in, and wishing I greased up, I managed 12 lenghts before needing to get out.

The pool was at best 25 degrees, when normally in summer it is chilled to 29, but on a cool January's night it felt a lot colder.
