How to stay healthy for longer time
Staying healthy and living longer are two most common wishes of people after 50. It's usually the time when people start noticing that their bodies don't act like they used to, they become more fragile, less flexible, etc. (if you are over 50 you don't need anyone to tell you what you feel, and if you are still 'under-aged', better not think about it too much, just know that nothing good will happen after 50... unless...).
Unless...
For your great grandparents in last centuries reaching 60 in good overall health was really hard, reaching 70 was an extraordinary achievement and 80, well... When your great grandparents were 80, everybody knew.
Nowadays, on the other hand, you may be 60 and still be quite active (just look at..., ok. Let's not point fingers at anyone because it's not nice to say how old people are, isn't it, or maybe...), you can be 70 and run marathons (check here: Ed Whitlock) in less than 3 hours (yes, it's possible), you can be 90 and still be able to get your PhD (it happened at least once - in March 2016, you can check it here: Colette Bourlier (1) and here: Colette Bourlier (2)), you can be 100 and even more and... well, you know...

Ageing -
introduction.
Causes...
What causes it? What slows it down? What could speed up the research progress?
There are three questions important in ageing research that are the topic of this article: what causes ageing, how can we slow down (or maybe reverse) age-related changes, and how can we speed up the progress in ageing research. This article starts in the first part with theories of ageing and moves to observations about ageing of human superorganism at different body levels: molecular, cellular, tissue, organ, extracellular, and the body systems level...
Leonard Hayflick wrote in 2007 that “biological ageing is no longer an unsolved problem”, but there is still a lot to understand about it and asked the important question: “Why then are we not devoting significantly greater resources to understanding more about the greatest risk factor for every age-associated pathology by attempting to answer this fundamental question: “What changes occur in biomolecules that lead to the manifestations of ageing at higher orders of complexity and then increase vulnerability to all age-associated pathology?” (Hayflick, 2007).
During last ten years a lot happened in ageing research... (read more)
Your
superorganism
in numbers
Top 9 numbers you should know about your super organism (super body)
if you want to sound smart at a party.
To better deal with ageing, it's good to know a bit about an organism you have (and that knowledge also helps at some parties). So, have you ever wondered how big you actually are?
As you know, human body is kind of a complex entity (usually). On the most general level it's only one human being, but underneath there are hundreds/thousands/millions of systems, organs, cells...
Well, do you know how many exactly? If you want to find out about number of body systems, organs, tissue types, cell types, brain cells, body cells, etc. that are in one human, you are in the right place.
So...
Let's start with something simple... (read more)
How to
search for
longevity?
There are different answers to this question...
(1)
You may try to find ways to alter any of processes that scientists believe are important in aging (López-Otin, Blasco, Partridge, Serrano and Kroemer, 2013, p. 1194):
- genomic instability,
- telomere attrition,
- epigenetic alterations,
- loss of proteostasis,
- deregulated nutrient sensing,
- mitochondrial dysfunction,
- cellular senescence,
- stem cell exhaustion,
- altered intercellular communication.
Just remember that some of these processes are more crucial to aging than others, they create the chain of changes (one process leads to another, e.g. telomere attrition leads to cellular senescence).
You may try to find the ways to repair/rejuvenate our bodies by dealing with... (read more)
Can people
stop dying
of old age?
People live... people age... people die... People die because of many causes and one of the most influential cause for dying in our time is "time itself". And to be more precise, millions of people "die because of old age". Of course, they don't die just because they are old, but they die because (1) their immunological system doesn't work in later years as good as it worked earlier and people are more prone to illnesses, because (2) their muscles are weaker (for example, heart muscle), because (3) their brains stop giving right commands to the rest of their bodies, etc..
But what if it didn't have to be like that? What if...?
And that's where the questions start... and there's where we start... (read more)
