New research links a lack of exercise to cancer, diabetes and heart disease – a triple threat combination that causes approximately the same number of fatalities as smoking.
The four research papers published online July 18 in The Lancet said inactivity-related risk for major killers such as breast and colon cancer, type 2 diabetes and heart disease amounts to roughly one out of every 10 deaths globally, a tally more or less equivalent to the number of people who die as a result of smoking.
