Walking Instead of Driving

As a nation, it seems our priorities are mixed up.  Time and time again, we hear about the price of gas.  However, when is the last time you heard that we need to put an emphasis on walking more, as a nation?  Walking is great for cardiovascular health.  Heart disease is right up there with the leading causes of death.  And, not only that, treating heart disease is very expensive.  I would bet that we could save more with walking than we could ever save with gasoline.  I don’t really care what the price of gas is; what I want to hear about is how we should be walking instead of driving.  In fact, our priorities are so mixed up that many of us have to go for a drive in order to go for a walk.  That should never be the case.  Physical fitness equates to happiness, but driving a car only loosely correlates to overall happiness.  Walking gets our endorphins going, and that is a natural high!  The effect of buying an expensive car often wears off.  But, many people need to be able to drive in order to do things like obtain their basic necessities.  In my opinion, we should be prepared for such a crisis.  Right now the best solution seems to be to have a system for delivering food.  There may be a market for food delivery for the elderly now.  However, that market could be really expanded in the case of a gasoline crisis.  It could operate just like the postal service.  So, perhaps, it is time to start implement localized food delivery systems.
