Im like Phil, this is very intersting.
Ive had the EXACT same irregular heartbeat my entire life and have just lived with it. Maybe its our Scotch Irish heritage Al! The doctors I've spoken to havent been too concerned, and told me just to live with it. I drink a bunch of coffee and maybe it would help if I stopped. Also interesting on the chemicals...My mother died of bladder cancer 2 years ago at age 88, the doctors asked me if she ever worked in an environment with certain chemicals, like solvents. I told him not that i know of.
We all need to watch our sugar intake more than anything, I believe Sugar has been linked to cancer for sure. I remember talking with the doctors after finding out if my moms cancer had spread to her lymph nodes. He said the test they perform is basically inject a high dose sugar shot in her blood before an X ray. Her lymph nodes lit up like a Christmas tree. It was ceratinly horrible news. She was 88 and lived a great life, watching all her kids live happy, productive lives. Please watch your sugar intake everyone.
