according to Dr. Garth Davis of UTHealth (University of Texas), a huge part of Western society's health problems can be traced to too much consumption of land animal fats and proteins.  Studies of the pockets of longevity on this planet (the blue zones, as they are called), such as Okinawa, Japan, some of the Greek Isles, the Seventh Day Adventist colony in Loma Linda, California, and others, show that the thing they have in common is the plant-based diet.  Cutting meat down to just a few times a week reduces your chances of getting cancer, diabetes, and heart disease drastically.  Best to keep one's diet to plants and fish for the most part, as I have done for a bit over a year, when Dr. Davis came to speak at my former employer, Broadcom.  So far so good, and I don't find it terribly difficult to avoid meat, seafood (not a fan anyway), eggs, and dairy products.  I love fish as long as it's cooked, so I eat quite a lot of it.  Yum!  I'm planning to be around for another 50 years at least (I'm coming up on 52 now), not so much for me, as I am a born-again Christian and am ready to go from this earth at any time, but to not be a burden on my family and on society.  I look forward to playing with my grandchildren and great-grandchildren someday :)  Eat fish and plants (better use of land area than raising food animals anyway) and live long and prosper!

@betajet - I knew there was a reason I took Latin and French (as well as Spanish and German) in high school!

I'll pass on the illustration!  LOL!

@Kevin: ...I think the idea of telomeres has been oversimplified...

I 100% agree -- I gave a very short account of this here -- the author of the Genome book also adds lots of qualifications -- there are other things that can go wrong in cells. However, he also notes that:

"...there is great variety in telomere length between different people, from about 7,000 DNA 'letters' to about 10,000 per chromosome end. And telomere length is strongly inherited, as is longevity. People from long-lived families, in which members regularly reach ninety, may have longer telomeres, that take longer to fray, than the rest of us."

@kevin: I don't think I believe that story about the mutation that makes you immune to all viruses...

I think he said practically all viruses -- I just spent a lot of time skimming through the book but I didn't spot that reference again and I don't have the time to go through page-by-page -- it certainly made me sit up and think.

@Crusty: Oh you flatterer, you know my cronological history, if I ever get it finished.

Cronological History, or Crustalogical History?

I think the idea of telomeres has been oversimplified.  It's nice to say that there is this one thing you can do to stop aging, but it's probably not true.  There is no theoretical reason why aging is necessary, though.  The body is just poorly designed.  It's a digital system, but still can't copy without errors.  And all of the cells in the body are replaced every few years, but do you end up with a new system?  No, you get a cloudy lens with weak focusing muscles but brand-new cells, which is little comfort.  It's like replacing the warped boards on the side of your house with brand-new warped boards.

Evolution just doesn't favor aging that well.  There is a tradeoff between long life and time between generations.  Long life has advantages in accumulating knowledge and passing it on, but a short time between generations is much more important in evolution and swamping your competitors.  And a short time between generations means a younger age at reproduction, and when a species reproduces young, any diseases that don't manifest themselves until a later age get passed on.  If women give birth before 30, there will be no natural selection pressure on a disease that starts at 40, or any senescense that occurs after that age.

@Crusty: ...So I live life to the full, in the best possible way I know...

All I know is that when we chatted on the phone a couple of years ago, you had a very youthful-sounding voice full o vim and vigour -- from a blind phone conversation I would have guessed your age at 35 to 40 -- hopefully that's good news :-)
