Your cells are a comary of 10.000 million tons, each devoted in some intensively specine way to your overall well being. There isn't a thing they don't do for you. They let you feel
pleasure and form thouse Thev enable you to stand and stretch When you eat, they extract
the nutrients, disuihute the enemy, and carry all the wastes, but they also remember to make
you hungry in the fietplace and reward you with the feeling of well being afterwards, so that
you went forget to eat again. They keep your hair growing, your ears waxed, and your brain
quietly puning. They manage every corner of your hoing. They will jump to your defence the
Instant you are threatened. They will hesitatingly dle for you tomor them do so delly,
nee all your years have you thanked even one of them. No, let us take a moment
How to reward them with the wonder and the appreciation they deserve.
Suprises at the cellular level um up all the time. In nature, nitrie oxide is a formidable toxin
and a common component of air pollution. So, scientists were surprised when, in the mid-
1980s, they found it being produced in ourlously devoted manner in human cells. Its
purpose was at first a mystery, but then scientists began to find it all over the place
controllingthe flow of blood and the energy level of cells, attacking cancers and other
pathogens, regulating the sense of smell. It also explained why nitroglycerin, the well known
explosive, soothes the heart pain known as angina (It is converted into nitrio oxide in the
Woodstream, relaxing the muscle linings of vessels, allowing blood to flow more freely.) In
barely the space of a decade, this one gassy substance went from extraneous toxin to
ubiquitous elixir
Rarely does any living coll last more than a month or so, but there are some notable
exceptions, Liver cells can survive for years, though the components within them may be
renewed every few days. Brain cells last as long as you do. You are issued with a hundred
Nillion or so at birth and that is all you are over going to get li is estimated that you lose 500
of them an hourso, if you have any serious thinking to do, then on no account should you
waste a single moment. The good news is that the individual components of your brain cells
are constantly renewed so that, as with the liver cells, no part of them is actually likely to be
more than about a month old. Indeed, it has been suggested that there isn't a single bit of any
nosso much as a stray molecule that was part of us nine years ago. It may not feel
like it, but at the cellular level we are all youngsters​
