Rahn I also don't know if the original reference was to L-dopa or not, but I do know that L-dopa will not be the drug to give long life. It is presently used as a drug to treat Parkinsons disese because it can cross the blood-brain barrier and is converted to dopamine. In normal humans it can have numerous side effects including memory problems and muscle movement problems. The Fountain of Youth is not with us and probably won't be.
