o Inactive men face nearly four times the risk of developing diabetes compared with fit, physically active men:

o Men who maintain physical fitness during their 30s have a significantly reduced risk of impaired glucose tolerance during their 50s:

o High-risk patients with Type 2 diabetes who cannot exercise for a variety of health reasons were seven times more likely to die from a heart attack than similar patients who were able to exercise:
