Here are two excellent articles about fitting in exercise to a busy schedule and the importance of a fit lifestyle. Business and making money should never take priority over a healthy life.
A major cautionary life cut short because of an unhealthy life style that was devoted mainly to business achievement, is that of Larry H. Miller. If you live in the west you have most likely heard of Larry Miller because he owned the Utah Jazz of the NBA, and 60 automotive dealerships in Utah, Colorado, Arizona and New Mexico. In his autobiography Driven published in 2010 (a year after his death at age 64) he admits he got so caught up in work he would sometimes go all day without eating, even though he had Type 2 diabetes. In his younger days he had been an excellent fast pitch softball pitcher, but stopped exercise after that. As he began to have major health problems in latter years he writes in Driven (p. 294) “The lesson of course, is to take care of yourself, to make time to eat and sleep and exercise. I learned that lesson too late”. He had a heart attack in 2008. And then had many other health problems, such as calciphylaxis where his blood vessels filled with calcium preventing oxygen from reaching his tissues. His legs turned black as a result, and in a last ditch effort to remain alive his legs were amputated 6 inches below his knees. His legs continued to turn black and he discontinued dialysis, realizing death was near.
