I was at an ideas festival filled with some bright and accomplished people and I found myself rebuked by what I would consider true ignorance at least three times.
In my search for wisdom about aging, I maintain that the primary cause is telomere shortening. This does not mean that methylation, signaling with stem cell produced vesicles (like packages with a purpose) don’t play a secondary role.
When we discuss the risk of telomere length to cancer risk, there are many studies but the conclusions we reach are limited by our simplistic assumptions.
Instead of being thrown off the the trail by the differences, we should find the commonalities. Both models of aging- oxidative damage and telomere shortening cause chromosome disruption and bone marrow mesenchymal stem cell damage and depletion.
This week, the future became the present, as scientists published a study showing that an engineered molecule that facilitates cell death could reverse signs of aging in mice and hopefully cure aging
