Ironically, I just sent an enthusiastic email back home to the US, extolling the health virtues of PhD life! I am getting a lot of exercise walking to and from the University, and around the city centre, about 15-20 minutes each way, and I just had the most marvellous shopping trip to a local outdoor market where I hauled away the makings of a feast--Italian ham and sausage, fresh bread, olive oil, garlic, onions, peppers--a big pasta feast for me tonight!
