That's why I tend to be very careful about not taking drugs, unless I already have a disorder that needs fixing, and unless advised to take them by a doctor I trust. Taking drugs to increase performances sounds a bit like overclocking CPUs. Sure they'll go faster... but at the risk of increasing bugs, and of a shorter lifespan due to increased heating.

The analogy works well when considering stimulants. However when considering drugs or supplements that are neuroprotective or that actively promote neurogenesis the analogy becomes fallacious. Cerebrolysin, for example is more analogous to opening up your computer and replacing the CPU and RAM with more powerful and more reliable components. Sure, it is invasive and requires caution and knowledge to do but the life expectancy of the core components is increased, not decreased.
