So there does seem to be some efficacy of new Pepped and Racetams. and things like it. It's an emerging area and as I mentioned in the U.S. these things are sold over the counter. Again, you have to figure out if it's right for you, but they are beginning to show some promise, and I'm intrigued by them because of the way that they tap into the cholinergic system, which is both directly involved in focus, and the ability to focus, but is also important for things related to age-related cognitive decline. So a decline in cholinergic transmission or acetylcholine as we call it in the brain is one of the things associated with cognitive decline and it does seem that increasing cholinergic transmission can offset some of that cognitive decline and perhaps even more so in conditions such as vascular damage or concussion to the brain.
