Teeny weenie batteries for a thing that spins round a lot. Not to power the spinning but to count the spin.
No this is not some LHC experiment from CERN*. The size of the power units required ought to be a give away to that.
The batteries are for a Powerball, a device which supposedly helps in strengthening wrists and grip.
I'm not overly convinced that the device does what it says, the medical evidence is thin on the ground.
I certainly couldn't find anything other than hearsay or anecdotal evidence, no actual scientific data.
It's a coincidence that the batteries are sitting on a set of charts of warm up exercises for guitar - the Powerball is cited by some as helping strengthen hands for guitar playing.
The only reason I took a picture of them was to see what type the batteries were.
To paraphrase Peter Cook - The writing is too small for the human eye, which is what I am equipped with.
And it is possible to increase the size of the image just by using human fingers, which I am also equipped with, oh and a smart phone of course.
There may be exercises to reverse hardening of the lens in the eye, although I expect they would have difficulty holding the weights.
* Spin, let me Google that for you.
