Nostalgia

Was looking for info on exercise induced insomnia and other than the same sentence pasted to about 100 different sites all I really found was that a very few other people do seem to get this. Did though find Arthur Lydiard saying that anerobic exercise can lead to insomnia. That and many, many other negative things he claimed.

He caught my attention with that and furthermore in that he said anerobic (interval) training only needed to be added about 4 weeks before a race. That's all it took to get it to about as good as it was going to get while one can slowly improve for years and years by doing aerobic activity daily.

This does actually seem to be largely true. Looking at lifting weights for example. Strength to body weight ratios hardly change at all beyond the first few months (barring drugs). So I'm chucking my interval training and going to steady speed runs on as many days as I can manage. Possibly might try to do 40 miles per week... And once a week, a single 1 mile time trial. Not quite what he advocated but we'll see how it goes.

Supposedly exercise is good for sperm but only if it's "moderate". I don't know how moderate is defined. Apparently 100 miles per week is beyond moderate. Is 30/40 miles a week? I don't know. I have noticed in the past that with daily steady runs I feel increased libido, perhaps that will tell me.
