late experimentation on everything from roundworms to mice are giving some scientist hope that our maximum life span are not lay out in stone but can be unfold far beyond what nature intended .
In many ways , tremendous progress has already been made in extending human life . From lowering infant mortality rate ( the biggest broker ) to creating in force vaccines and reducing decease related to heart problems , science has helped increase theaverage person ’s liveliness spanby nearly three decades over the past century .
But getting the average soul from 80 to 120 and beyond require inquiry into the verycellular mechanismsthatcause gray hairandwrinkles , that make ourbones creakand ourminds go weakly , and what broadly make all creatures shrivel , shrink and rot away .
The big question : Cancell agingbe stanch or reversed ?
use up less
The first hint of the possibilities came in the 1930 ’s , when studies by Cornell University researchers discovered that rat fed severely reduced calories tended to survive up to 40 percent longer than their full fed littermates .
Scientists still are n’t sure how thermic confinement , or CR , cultivate . One early surmisal , that CR regimens extended life span by preventing animals from reaching full body size , was debunked when experiments showed that even in full grown grownup can profit from CR .
For about 50 years , CR was the only prove method acting to extend an organism ’s maximum living span in a healthy way .
Then in 1996 , scientist discovered a type of mutant dwarf mouse that lived up to 70 per centum longer than its non - mutated peers . The rodents ' scrawny growth was due to a modification at the transmitted layer that reduced production of hormone have-to doe with to ontogeny .
Genetic tinkering
In the years since , http://www.livescience.com/183 - life - expectancy - america - striking - record - high.htmlhas also create more enduring yeast , roundworms and yield flies .
Much of the anti - ageing research is still done on rodent , whose biological systems are alike to humans in many manner . In fact , a lead advocate of human anti - aging enquiry has organized a hefty booty for breakthroughs that extend the lives of black eye .
Scientists have also discovered other factors that affect life span in inquiry that might eventually be apply to humans . A subject area out of Cambridge University in England find that what a female parent eats during pregnancy and whilenursingcan greatly affect her children ’s life spans .
Using mice , the researchers found that mothers fed protein - rich diets during pregnancy , but low - protein diets while breast - feeding , had pup that lived up to 50 per centum longer than those for whom this feeding pattern was reverse . If a like approach could operate for humans , this translates into a departure between get to 50 and living to be 75 years old , the research worker said .
Get married
If the thought of run through only enough to survive or having your genes mucked with does n’t sound very likeable , scientist say there is another and perhaps more pleasurable way to live longer : fall in love .
A study earlier this year top by Linda Waite , a sociologist at the University of Chicago , showed thathappily wed couplestend to last longer than unwed individuals . Married men were found to live , on ordinary , 10 years longer than non - married men , and married char lived about four years longer than non - married cleaning woman .
The researcher speculate that married man live longer because they embrace healthier life style and take fewer risk . Married woman , on the other hired man , probably live longer because of the improved fiscal well - being that comes with union .
