From my experience the problem has a few facets. I recall a quote “Most folks are about as happy as they make up their minds to be.”
The same might be said in a large measure about health.
When you talk to people about improving their health and longevity most are not interested or pay lip service.
When my wife Julie was spending $2,000,000 a year on clothes (fortunately I did not have to pay the bill, she was a fashion buyer for 25 shops) one time a supplier held up a garment for her and said, “This is for the fashion victims.”
Julie queried him and he responded, “A ‘fashion victim’ is someone who will buy the latest fashion item regardless of whether or not it looks good on them or not.” Remember muffin tops?
Most people are taste victims, they eat what tastes good, regardless of whether or not it is destructive to their health. Sugar is addictive. Apparently 8 times more addictive than cocaine. If you want to be successful we should set up a Sugarholics Anonymous for the taste victims!
