Staying healthy is very important. Specially as it is assumed that about 80% of the health issues people face are caused by nutrition or lifestyle.
I made and gave to every family member a set of such Brock Strings. It is a poor excuse to claim the eyesight is deteriorating with age, it is deteriorating also because of lack of training and exercise (and occasionally because of stress and too long exposure to screens).
I am an example who got rid of 35 years eyeglasses and I am now driving and reading without any glasses … but it needs regular focus on this important organ … our eyes.
