Age seems to have a major negative effect on LD ability. This is undoubtedly due to the decreasing neurotransmitter levels in the aging brain. That is why I think it can be very helpful to take "psychoactive nutrients" such as fish, salads, B6, B12, Calea Z (don't make a tea, put the stuff into CAPSULES ), choline, DMAE, vinpocetine, phenylalanine, galantamine, huperzine, wormwood, mugwort, and last but not least -- chocolate milk.

The nice thing about chocolate milk is that the chocolate contains caffeine and theobromine -- which have a stimulating effect -- and the milk contains tryptophan -- which helps you stay asleep. Thus chocolate milk kills TWO proverbial birds with a single stone.

Good technique is only part of the answer. Good "psychonutrition" is equally important. No matter how powerful your car, it ain't goin' nowhere if there's no gas in the tank....
