I’ve been hearing this for 50 years now.
Along with algae into gasoline.
Flying cars.
And the carburetor that gets over 6000 miles per gallon.
My hair was getting thin, but not bald, after 76 years, when I started using a red-light cap for twelve minutes every day. I will understand if you do not believe me, because the results are incredible, but after only four months, my hair is as thick as when I was twenty. Even more astonishing, the grey has disappeared. You can believe it r not, but I am not joking,
