Blog-watch: aging and longevity

July 22nd, 2010 · No Comments · Psychology

Any regular readers will be well-versed with my genuine life goals an motivations by now.  The quick and dirty summary is that I want to be able to live until I am a centenarian but I would like to be fully active and self-sufficient (eg. able to care for myself) all the way through.  This drives a lot of my diet, exercise and other lifestyle choices.

I'd like to still be doing this when I'm 90!

Some time ago I did a blog-watch about longevity and this is a brief update with a few recent articles, thoughts and findings about how to achieve this.

  • Sirt1 is a protein which is one of the mechanisms by which calorie restriction prolongs life in yeast and worms.  NephroPal has pulled up some studies looking at this protein and summarised them in the context of the evolutionary “Summer” and “Winter” modes.  It’s well worth a read and the conclusion I drew from it was that we should be looking at trying to follow a more seasonal diet and fasting/non-fasting pattern to achieve longevity.
  • Looking a bit more at intermittent fasting and longevity, the Inhuman Experiment blog has done a summary/comparison of various studies looking at the issue of intermittent fasting and longevity which is well worth scanning through.
  • There was a slightly depressing study highlighted by Chris on Conditioning Research suggesting that sarcopenia (loss of muscle as you age) is not just caused by older people being less active, but is potentially down to metabolic changes and perhaps isn’t as controllable as previously thought.  As Chris points out, the study was based on people undertaking endurance training and it’s worth considering people like Clarence Bass when looking at how resistance training fits in with this.
  • It’s worth reading the review of BioMarkers, written up by Chris at The Garage Gym Online (and the guy I share my life with, before anyone accuses me of not revealing related interests).  Biomarkers is about the signals for aging and how to reduce or prevent these and is therefore an important read for anyone who is concerned about aging and ensuring visual and physical longevity.
  • Finally, I got a good laugh out of the graph shared by Brad Pilon on his blog.  This seemed to suggest that, if you start out age 20 on all the things they suggest, you could add 60-80 years to your lifespan.  Since I come from a family of reasonably long-lifers (at least they’ve certainly all made it to at least their late eighties on my mother’s side) this implies that I could live to 160?  I think not!

For anyone interested in longevity and long-term health and well-being I hope these are helpful for you.  If you find other articles on this topic please let me know – I’m always glad to hear more ideas on how to achieve my life ambition.
