I'm not really a relaxation person. I like to be doing stuff, and although some of my staff think I'm crazy for this, working at the lab, doing routine benchwork of the likes the techs do all week long, is something I find relaxing. I do. Pipetting hundreds of samples and transferring them from one machine to another is a mental vacation for me. The hands work, the mind wanders. It's a welcome change from my usual work, which involves sitting in my office reading papers and checking data and writing reports.
I do relax at home in the evenings. Usually I knit or work sudokus while watching an hour or two of tv. Very photogenic. Sometimes I spend time in the garden, my oft-photographed garden, watering the veg and the flowers, pulling weeds (yes, really, there are just so many it's hard to appreciate that there are fewer than there might be), picking what's ripe, chasing the cats, and a new activity: mowing the lawn.
And, every once in a while near the end of a weekend afternoon, I pour a glass of cold Chardonnay and take a good book out to the garden.
