Leonard Hayflick Limit ( Theory ) 1961
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 I feel personally the study is outdated and new evidence through science has proved the theory incorrect.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 youâ€™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 pathologiesâ€“as well as in cancer developmentâ€“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 nowâ€“safely and effectivelyâ€“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.
