Of course, I wasn't around then either. But our daily load of physical activity now compared to then is drastically different. Their portions were much smaller as well.
That piece of information was shared to me after my father and uncle both went into the ER for a Quad By-pass and the other a stroke, nearly back to back. The gentleman that shared that with me is a trainer that the studios down here use for cast members on TV or Films - which is a ruthless game down here. I had a lot of emotion after almost losing my father and when I walked into the gym I went straight to him and told him what happened and it was a family trait and I needed to do something..now. So he pulled me aside and he opened our conversation with that line.. very thankful for that day. After more than a dozen swings of around 50lbs in weight over my life, I've never had more control.
