Mistaken concerning stretching. Randomized controlled trials may show that done before competition it decreases performance and there may be no proof it decreases injury but it actually does make my knees feel better. Immediately so even. Especially 10 hours into a hard 13 hour work shift.

In part from reading Roger Bannister's autobiography I completely got rid of the slower running and was just doing intervals and that was a mistake. Running at a basically comfortable speed has to be the basis of a running regime. Doing so gives a positive carryover into the rest of one's life. Gives stamina. Interval training seems to just make me want to lay around and do nothing.

Bought strength shoes hoping to help my knees, right knee especially. Ran in them for third time today. Did half a mile. Years ago I had such extreme soreness just from running a lap. The bicycling I think has my calves more able to handle the shoes this time. Barely any soreness at all so far.

Reading The China Study has me wanting to get back to perfect veganism and also a lower fat diet. Also some constipation (having to push a bit) that eventually I figure will lead to hemmorhoids if I don't make an intervention. Also worry about BPH. So I got rid of bread, pasta and a bunch of fat and now when I stand up I almost pass out. Also had serious gastric upset the other day. (Of course at work. The worst possible time. What hell it is to feel bad in the middle of a 13 hour work day trying to take care of very sick people.) Strangely reducing my fat intake has always resulted in feeling lightheaded. I don't think it's the lack of total calories. I eat a bit of fat and always feel better. And I know it's not just a short term adjustmental issue as I've stuck with such a diet for up to a year.

The China study is a bit vague on whether the optimum diet is low fat, low protein, or simply vegan. The two aren't necessarily the same.
