Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
Ellsworth Wareham
Loma Linda, Wareham's home town has been described as USA's only Blue Zone, an area where the longevity is appreciably higher than the national average and one of the four places in the world to have a substantial proportion of humans live past 100 years. The city has strict controls on the sale of alcohol, has a ban on smoking, and its largest supermarket does not sell meat. Wareham attributes his longevity to having adopted a vegan plant based diet about fifty years ago. Wareham's video "Dr. Ellsworth Wareham's Secret for Staying Young" has been featured on AOL, and tv.com. Wareham appears in "How to Live Forever", a documentary film about longevity. He has also presented talks on preventative medicine and what he believes constitutes a long healthful life.
