Longevity in developed
and in developing countries
3Part 1- Long-lived individuals & groups
* The U.S. Census Bureau view on the future of longevity is that life expectancy in the United States will be in the mid-80s by 2050 (up from 77.85 in 2006) and will top out eventually in the low 90s.
* Recent increases in the rates of lifestyle diseases, such as obesity, diabetes, hypertension, and heart disease, may drastically slow or reverse this trend toward increasing life expectancy in the developed world.
Future trends
4Part 1- Long-lived individuals & groups
* Very little sickness, longest,disability-free life expectancy on planet* Mean age of 81.2, highest percentage of centenarians (40 per 100,000)* Use nutrient dense, plant-based diet,cultural traditions, elder care, and Reiki (Healing Art) for wellness* 78% of entire food intake is comprised of vegetables, rice, seaweed, sweet potatoes, fish, legumes, and tumeric* Protein comes from fish, nuts, tofu, chicken or pork. Consumes lot's of Omega 3 fatty acids

6Part 2- The aging process & Hayflick limit
* Leonard Hayflick demonstrated in 1961 at the Wistar Institute, Philadelphia, that a population of normal human fetal cells in a cell culture divide between 40 and 60 times.
* This limited capacity to replicate is called the Hayflick limit.
* When cells reach this limit, they undergo morphological and biochemical changes that eventually lead to arrest of cell proliferation a processes called cell senescence.
Where does the aging come from?
7Part 2- The aging process & Hayflick limit
* The Hayflick limit has beenfound to correlate with thelength of the telomere region at the end of a strand of DNA.
* During the process of DNA replication, small segments of DNA at each end of the DNA strand (or telomeres) are unable to be copied and are lost after each time DNA is duplicated.
* The telomere region of DNA does not code for any protein; it is simply a repeated code on the end region of DNA that is lost.
* After many divisions, the telomeres become depleted and the cell begins apoptosis. This is a mechanism that prevents replication error that would cause mutations in DNA.
Telomere, protective DNA tips which can not be copied
8Part 2- The aging process & Hayflick limit
* This inability to continue to divide iscalled Cellular senescence* Still, recent investigation has unveileda more complex picture.* Not all single cells do accumulateage-related damage.* During mitosis, the process by which a cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei),* the debris is not evenly divided between the new cells. Instead it passes to one of the cells leaving the other cell pristine.* With successive generations the cell population therefore becomes a mosaic of cells with half ageless and the rest with varying degrees of senescence.

9Part 3- Factors affecting longevity
* Who you are and can not changegender, genetics
* Where you liveaccess to healthcare and crime rates
* How you livehygiene, diet/nutrition, exercise & lifestyle
Significant factors in life expectancy include:
Approximately 20-30% of an individual’s lifespan is related to genetics, the rest is due to individual behaviors and environmental factors which can be
modified (source: wikipedia)

Let's look first at genetics: the meta-study below estimates genetics to have an approx. 20% impact on life expectancy
