It's Monday morning. On Wednesday I plan to head up to the Fannaichs, a group of hills near Loch Fannich about 4½ hours drive north of Edinburgh - up into the 'real' Scotland. I'm feeling fairly nervous about it. Is this really the time of life for a 58 year old who has very limited experience of camping to be heading off into the wild for four or five days on his own?! Maybe it is. What am I doing this for ... and why am I writing in the blog about it?

Common sense isn’t common, at least with healthy behaviours. The vast majority of us know that we should eat sensibly, be a reasonable weight, exercise regularly, not abuse alcohol, and avoid smoking. Do you know what percentage of people actually follow all this obvious advice? A survey (Reeves and Rafferty 2005) of over 153,000 US adults in 2000 found that only 3% ticked all four boxes when asked if they didn’t smoke, were a healthy weight (body mass index, calculated as weight in kilograms divided by square of height in meters, 18.5 to 25.0), consumed 5 or more portions of fruit and vegetables daily, and exercised in leisure time for at least 30 minutes, 5 or more times per week (this includes brisk walking).
