I sow film about our brain - sensory connections, and work /National Geographic/.
There was - recognition /proper/fast response test .
i did it for the fun, and get the top of the scale, superhuman results
I was very proud of myself couple of sec., ...until I get info , that my age is below 30 years o.! /I`m close to 60/
What is credibility of such semi- science tests?
Is it pure fun or something more?. N.G., seems to be pretty solid tv channel .
