Very nice job, Robyn. You’ve a well-inked pen.

surprised with our own desire to stay/look youthful this hasn’t been studied in more depth!!! so interesting!

What an interesting story Robin. I suppose there is a lot of facts and studies done that Negligible Senescence really do have an impact to our trees and animals. Deterioration in age is devastating and if it can be stopped it would be wonderful.

Hi Robyn, besides bacteria and yeast, hydra who’s able to regenerate its parts and more life forms, some jellyfish are matters of quite a few articles on the most important scientific magazines of physiology and biology, for example some regarding the jellyfish Tirrithopsis dohrnii in particular. Simplest organism sometimes are the ones that have a long life expectation. So far, this species in particular has been studied for further use in medicine. Nature is wonderful and perfect!

Absolutely fascinating Robyn. I thoroughly enjoy reading these scientific based articles as I learn so much.

This is fascinating Robyn, thank you for sharing. There are specific tests that we as humans can do to measure our biological age via telomere length. It is possible to reverse our biological age with lifestyle choices, where our markers may be aligned with someone several years younger than our chronological age, but as to whether or not it helps us appear more youthful is still up for debate. And whether this contributes to actual longevity is also probably one of those things that isn’t always the case. Regardless, this type of research is so interesting, and I look forward to seeing what else we learn in the coming decades.

Thanks, Robyn, for this interesting blog on aging. A fascinating topic, as we all, I guess, are not particularly fond of getting old. So it’s interesting to consider how other creatures cope with getting older.

This topic is endlessly fascinating Robyn! Thanks for your post.

Very interesting topic, Robin.
Could you please explain this a little more: “a leadwood tree can live up to 1070 ± 40 years”
Keep up the good work!
