Hi, I've read your post and I'm Older, 77 soon. I worked about 40 yrs and never had any of the issues you mention. I did have first signs of OA in lower back at 18, but got on with my life. Back in my days, computers were just coming on, I hardly used one until mid 80's when I worked for Hitachi and we used apple. I resisted the technology and computers from day 1, but again I'm Older...Many of my friends my age, NEVER even got on the computers...

I don't know and no one will ever know if all this technology has done more damage than good. I do enjoy my desktop, but use no other technology to speak of. Very basic and old thinker on high tech, but I am a "thinker"....

I've been taking grape seed extract, powerful antoixidant, for 20 yrs soon. This can't hurt you but sounds like a lot more going on.

Magnesium deficiency is alive and well out there and you mention cramps, muscles etc..check out magnesium in your blood levels for starters. This comes to my mind first on all you mention.
