Second Wind
Lomita, California
Dear Friends:
On a recent trip to Denmark, I learned that windmills make 10% of the
electric energy for all of Denmark, based on the presence of almost continuous
sea breezes. A string of large
rotor propellers faithfully churn out millions of kilowatts for the growing
appetite of a modern electric-oriented western country with a high standard of
living. This means fuel for a
myriad of brightly lighted hotels, factories, stores, and heating, which is
currently done largely by electricity, at least in Copenhagen.
The windmills only make energy when they are turning (moving).
I mused over this recently as I considered the energy needed by
ourselves. We need to deliver
oxygen to tissues to allow the consumption of foodstuffs in a process known as
metabolism, for high energy production. The
transport of oxygenated blood to the tissues provides an abundant supply for
tissue metabolism. Exercise works
to promote increased energy production. If
the windmill stands still, no energy is produced.
As we sit and do nothing, we limit the energy supply to our tissues.
We need to move briskly, as do the windmills, to make more energy for
life and the pursuit of happiness.
I will be in touch next month.
Your
friend,

Thomas Petty, MD
