How Important is Health?

Better question:  How much is health a liability with your company? Does it affect your productivity?

Japan recently enacted a LAW that FINES Japanese workers who are overweight (due to their rising obesity percentages).  Apparently Lincoln Industries also has a requirement for employees to be physically fit. I think this is a great trend.  As much as I would love to say it is one’s own freedom to gain as much weight or smoke as many cigarettes as he/she sees fit, a company has a responsibility to its employees and itself.  Not only would fit employees increase productivity, it would also increase happiness and decrease potential liability and risk.  Why aren’t more companies doing this?  What are your thoughts?
