The Department of Health has recently launched a website to measure and improve your health at mid-life. See www.midlifecheck.co.uk It is designed for people over the age of 40 so that seems to be when "mid-life" starts for the DoH. (Research I've conducted over recent years suggest that most middle-aged people don't regard themselves as middle-aged so possibly an issue on the self-identity subject).
However, I've just keyed in my answers and have been reasonably impressed with the process. It provides really useful and probably uncomfortable information about alcoholic units as well as realistic suggestions about how to increase physical activity which are probably quite easy to do if we are prepared to make changes.
It enables you to save your plan and to check progress over time and I shall be forwarding it to some of my friends as it's quite fun to do.
I'm not that keen on the Doctor who kept on appearing and talking to me, not sure if that is supposed to give me the personal touch but I couldn't quite find how to turn her off (you can have a male Doctor if you prefer!).
