Will it fix stupid?
If you are happy that lab mice have been given things that improved their mouse cognitive ability. Along with improving it with older mice by setting their physical condition back to a younger age. Then it is probable a protein trigger will be turned into a therapy to gain humans some IQ points. And a few points in the lab with mice at least is all it took to see a world of difference between stupid and able to learn.
Now what people do with a few IQ points, is that your threshold for stupid? Some people just don't use what they have. The common factor amongst small business owners that determined their success in the U.S. at least. A very high level of persistence at what they were doing. Just hanging in there and grinding away day after, week after, month after year.
The rest of us colonials just sit on our couches eating pie and listening to Oprah. That must be where our IQs went....
Now I remember, but, that was some time back when I thought I forgot. More pie will fix everything......
