TENS- Wow Old School Stuff like 1920's

G' Day,
I forget when but we started using Tens + or - 30/40 years ago and still in use for my self, people like Bruce Lee were using and promo Them, we were into T'ai Chi and the soft M. Arts. my self today at 84 still teaching T'ai Chi, Still Paddle a Surf Ski on open water were I may say they belong, Still riding Single Speed Mt Bikes and living the good live teaching Older people how to breath and move ox about the body. I feel using the Tens for a week or so when trying to work out a health problem is the way to go, IT is not to be an every day thing, also single malt, an Oz beer and keeping busy seems to work well for my self.
Cheers Joseph

Enlighten me, what does Tens refer to? I am not familiar with the term in this context.

Thanks

@McClms, guess he refers to the above ...
