1 Don’t even think about smoking and, preferably, don’t hang glide.
2 Eliminate sugar to lower blood insulin levels. Use stevia as a sweetener. It is a South American plant that is both very sweet and good for you.
3 Don’t eat any animal fats. Government guidelies tend to say cut these down, but they probably only say this because they think it’s the best people can manage. No saturated fat at all is probably best.
4 Eat lots of vegetables that grow above ground. Those below ground are heavy in carbohydrates that turn into sugar and raise insulin levels.
5 Don’t overdo the fruit. Contrary to popular wisdom it’s not unconditionally good as it contains sugar. Non-drinking Arabs and Indians who sit around sipping orange juice all day end up with diabetes.
6 Eat nuts. For incompletely understood reasons, people who eat nuts live longer. Not salted peanuts, however (see 7).
7 Don’t salt things. Salt raises blood pressure and will kill you through a stroke or heart attack. For this reason, don’t touch processed food.
8 Don’t have heart bypass surgery or have a stent installed to hold a blocked artery open. Latest figures suggest neither works. People who live longer after them probably do so because the shock made them eat better and exercise more.
9 Have a massive medical assessment, preferably at Kronos in Phoenix, Arizona, to establish what you are doing wrong and, if possible, what genetic weaknesses you have. Continue these assessments throughout your life and adjust supplements accordingly. Read all the latest medical journals to keep up.
10 Exercise vigorously and daily but don’t run. Running is bad for your skeleton.
11 Take a child’s aspirin once a day to thin your blood and a much larger dose before you get on a plane. Ideally, don’t get on a plane.
12 Eat very little. Rats on restricted diets live longer but it is not known if this would damage humans — particularly their brains. So if you forget what 2+2 equals, eat more.
13 Ignore all of the above. They may be wrong and, if a piano falls on you, pointless.
