I describe the mechanisms by which different wavelengths of light impact the cells, tissues and organs of the human body, and how specifically timed light exposure of specific wavelengths can be used to improve sleep, enhance alertness, modulate hormone levels, and improve mood. I also explain the use of ultraviolet and infrared phototherapies to relieve pain increase testosterone and estrogen levels; improve skin health, appearance and wound healing; and how red light can be used to offset age-related vision loss and provide neuroprotection. Throughout the episode, I describe the mechanisms of light-based therapies and actionable tools that people can use positively impact mental and physical health.

The concept of biological immortality challenges the belief that death gives meaning to life and raises questions about the potential societal implications and ethical considerations of living indefinitely.

Questions to inspire discussion.

What is biological immortality?
—Biological immortality refers to the potential for humans to live indefinitely due to advancements in science and technology, leading to the elimination of age-related diseases and the aging process.

I like the chapter “would you want to be”.

Ah, immortality, previously only for the gods and individuals with a fetish for chopping each other’s heads off. In more modern times, science is coming closer and closer to both identifying the tapestry of things that cause humans to grow old, and slowly but surely taking the first steps into finding ways to delay and even reverse this process for fun and profit. So, just what causes individuals of the human persuasion to grow old and die, who was the oldest confirmed human, are there any living things that are biologically immortal, and if there was an option to become biologically immortal, would you take it?

ALBERT LEA, Minnesota (WCCO) — Living to 100 may seem like a major feat, but there are communities around the world where it’s common — they’re called “Blue Zones.”

Minnesota native Dan Buettner is one of the foremost experts on how they work. Buettner’s new Netflix documentary and New York Times bestsellers reveal the secret recipe to longevity.

Amid the rubble of large-sale earthquake, war or other disaster—and as aging buildings and infrastructure are replaced—mountains of concrete are often taken to landfill or pounded into rubble for roads.

For a more sustainable approach, Flinders University and The University of Melbourne experts are developing a ‘value add’ for old broken concrete to ‘upcycling’ coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient—graphene.

The novel method is gaining ground every day as new graphene deposits are discovered and mined—bringing the price of that raw material down as the cost of cement and aggregates continues to rise, the researchers say.

So if I heard this right, after 8 minutes or so, the effects are temporary and he indicates people would have to take this every couple of years.

Cats already have 9 lives, but what if we could give them 18? Longevity research isn’t just benefiting humans: I looked into some supplements and products that may help you extend your cat’s lifespan, or at least their healthspan.


If you proudly share a house or apartment with one or more cats, chances are you want your precious pet to live a long and healthy life. In addition to getting the basics of diet, exercise, and safety right (basically, do the opposite of the cartoon Garfield), there are many cat longevity products out there that aim to increase your cat’s lifespan.

We’ve taken the time to explore some of them, and this comprehensive list of the top nine cat longevity products is a resource you can use to discover options that may keep that furry feline of yours not only healthy but also happy, energetic, and curious for many years to come.

Our list features cat nutrition products, including longevity cat food and joint care for cats products, as well as cat supplements, and some more unconventional cat health products like pet insurance. As always, we are highlighting high-quality, science-backed products that generally have research showing at least healthspan-, if not lifespan-, extending effects.
