Dr Dubal and Dr Mucke hope, despite their failure to show any protective effect of KL-VS on age-related cognitive decline, that this knowledge may be put to use.
A drug that elevates klotho levels, or mimics that protein's function, might indeed enhance cognition, and there is no obvious reason why such a drug should be restricted to the elderly.
If it could be developed everyone--except, maybe, those already in possession of a copy of KL-VS in their genes--might be able to take pills to make themselves a little brighter.
Sure. What could go wrong?
