Also on today's life extension kick: The Life Extension Foundation. Looks like a good idea at first, but the prices are similar to the prices locally at the health food store. They say this is because they use "premium products", and "Only high-quality" products. They still have some great multivitamins and admixtures of various things, and their information is awesome in some cases, but I don't know if I trust their buying program.

"Two amino acids, dl-phenylalanine and tyrosine (500 mg taken 2 or 3 times a day) are capable of elevating brain endorphin levels."
Thought this was really interesting.
