Leonard Hayflick Limit ( Theory ) 1961

http://sellingthefountainofyouth.com/?tag=leonard-hayflick


This scientist (leonard hayflick in the 1960's) basically claims through his theory that oxidative stress to cells cannot be manipulated . ??

How can this be ??


  Supposivly this scientist proved anti-aging tactics a mere marketing position . 

 The scientist basically ran an experiment that proved cells divide and there is no slowing them down or in other words. Oxidative stress on cells is inevitable . 

 This mans theory basically is contradictory for what Dave A claims.   I feel personally the study is outdated and new evidence through science has proved the theory incorrect. On a positive note,  Stem cells, when placed in cell environments, Old cells are actually taken over by newer younger cells. SO this is actually anti aging at its best.



Here is a short excerpt from a webpage speaking about Hayflicks theory. ::  

 
: As you know, there is a lot of misinformation out there about what has actually been proven to extend life (if anything). What is an example of an anti-aging claim that you’ve come across that you think has been overblown or improperly communicated to patients?


A: To start with the first part of your question, there is absolutely nothing that has proven to be effective extending life or even just preventing age-related diseases.


One of the most astonishing anti-aging claims that antioxidants will help people live young forever and avoid cancer and all diseases. While it is true that there is some good solid research on the possible role of oxidative stress as a mediator of the aging pathologies–as well as in cancer development–a clear causative role is far from being proven. The efficacy of an antioxidant intervention, therefore, is even further away from being established. If anything, when tested in clinical trials involving healthy volunteers, it showed that it is more detrimental than beneficial. Still, we constantly receive the message that we should be eating food and drinks containing plenty of antioxidants and even swallowing antioxidant supplements. There is no evidence and no scientific basis to think that this would do any good, only data showing how dangerous it might be.


Q: What is the one thing you tell people they can do right now–safely and effectively–to help extend their lives?


A: Even the more sensible health advice, based on reasonable assumptions, should not be advertized as capable of protecting us from aging or extending our life. Healthy habits such as some regular physical exercise, varied and balanced diet, staying fit and keeping an active network of relationships with friends and family, might not extend our lives, but surely they will make them more enjoyable.

    Aging in a cellular state starts at the mitochondria. Normally it is your eyes, brain, liver, endocrine system, and skin that first show signs of oxidation’s damaging effects and stress. This is aging. Deterioration of organs too are due to DNA replication failure. Replication process takes place every 7 to 8 years. It often replicates an inferior copy of the original DNA. The aim is to slow down the harmful effects of oxidation. We can do this to some degree on a cellular level and it is`nt a marketing myth. Take a look at the following supplements: PPQ, Zeaxanthin, Astaxanthin and Lutein. These are known as super antioxidants. Every now and again a new super antioxidant such as Noagin replaces the former. You might want to investigate stem cell transplants used to increase the chance of a cure or remission for various cancers and blood disorders.
