What's in my Wishlist now?

Well.. As you know i'm a student in UTAR (University Tak Ada Rehat) or The university that won't let you have any rest...
So what i actually want now in my wishlist is.... NOT Keyboard or any Musical instruments till i get into Degree..
What i want Now is Nootropic medicine...
also referred to as smart drugs, memory enhancers, and cognitive enhancers as well as intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that are purported to improve mental functions such as cognition, memory, intelligence, motivation, attention, and concentration. The word nootropic was coined in 1972 by the Romanian Dr. Corneliu E. Giurgea, derived from the Greek words νους nous, or "mind," and τρέπεινtrepein meaning "to bend/turn". Nootropics are thought to work by altering the availability of the brain's supply of neurochemicals (neurotransmitters, enzymes, and hormones), by improving the brain's oxygen supply, or by stimulating nerve growth. However the efficacy of nootropic substances, in most cases, has not been conclusively determined. This is complicated by the difficulty of defining and quantifying cognition and intelligence.

Racetams

The word nootropic was coined upon discovery of the effects of piracetam, developed in the 1960s.[19] Although piracetam is the most commonly taken nootropic,[19] there are many relatives in the family that have different potencies and side effects. Other common racetams include pramiracetam, oxiracetam, and aniracetam. There is no generally-accepted mechanism for racetams. In general, they show no affinity for the most important receptors, although modulation of most important centralneurotransmitters, including acetylcholine and glutamate, have been reported.[20] Although aniracetam and nebracetam show affinity for muscarinic receptors, only nefiracetam shows it at the nanomolar range. Racetams have been called "pharmacologically safe" drugs.[11]

Other substances sometimes classified as nootropics include hydergine, vinpocetine, bifemelane, huperzine A (cholinergic activator below), and dimethylaminoethanol (DMAE).[11



Let's not forget about Alcohol—moderate drinkers tend to have better cognitive function than abstainers or heavy drinkers
