How long does it take for most of the atoms in your body to be replaced by others?

Every 16 days about 72% of you is replaced.

About 72% of the human body is H2O (liquid water). Every ~16 days nearly 100% of the water is exchanged in a healthy body. Heavy elements like carbon, sodium and potassium take occupancy far longer perhaps 8 months - 11 months.  For example the calcium and phosphorus in bones are replaced in a dynamic crystal growth / dissolving process that will ultimately replace all bones in your body.

Other larger organs' atomic replacement can be estimated:

•The lining in stomach and intestine every 4 days
•The Gums are replaced every 2 weeks
•The Skin replaced every 4 weeks
•The Liver replaced every 6 weeks
•The Lining of blood vessels replaced every 6 months
•The Heart replaced every 6 months
•The Surface cells of digestion, top layer cells in the digestion process from our mouth through our large bowel are replaced every 5 minutes

In about a year every atom in your body would have been exchanged.  Not a single atom in your body resides there forever and there is a 100% chance that 1000s of other humans through history held some of the same atoms that you currently hold in your body.

Just as fascinating, is the fact that about 30% of your body, by weight, is not even "you" (cells without human DNA/RNA), it is a cooperative arrangement of bacteria, viruses, parasites and other welcomed or sometimes unwelcome guests.  In fact, just in the case of bacteria, there are 10 times more bacteria cells then human cells in your body.

^^  I think Libby asked a question along these lines at some point in our past conversations.

Locutus, you have a good memory. I've been trying to remember where/when I posted that. Can't remember if that's the one I copied from a science publication in which a scientist accounted for everything in a human body but had a little bit of 'space' left over, and he wondered if that was where the soul resided. Ever since I read Bo's post today, I've been trying to remember where I tucked that story away so I could find it again.

Ask and ye' shall receive.    I found it on the thread about followsthewolf when he died a couple of years ago.

These are two very good questions ...

this naturally raises significant questions for physiology and psychology: Where are the memories of a lifetime stored?  How is the sense of individual identity preserved through these numerous :re-embodiments:?'

Thank you, Locutus.     I wonder how long it would have taken me to remember that it's from my book on reincarnation. It's an old book I found somewhere years ago. Not a how-to or anything like that, just quotes and anecdotes from credible sources.

Which from where I sit on this trail of life, proves that with all of the knowledge of science that is available today, and even stipulating to all that the worlds religions claim to know, in reality we haven't even scratched the surface of what the reality of the true meaning of life- physical nor eternal, truly is. . .

Here's an interesting take from me on that subject...

We're not what we think are.  Humans are nothing but the means by which bacteria become mobile and sentient.

Well, I like to consider other possibilities, such as, bodies are temporary housing for souls. I'll leave speculation about why, how, for another time.  Or not. 

When earth's last picture is painted, and the tubes are twisted and dried,
When the oldest colors are faded, and the youngest critic has died;
We shall rest, and faith, we shall need it -- lie down for an aeon or two,
'Till the Master of all Good Workmen shall put us to work anew.

Scientists have found evidence of gravitational ripples in space, first predicted by Albert Einstein a century ago in his famous space-time theory.

More proof that Einstein was an advanced alien.

Step 1 ....

Bacteria are more impressive than they look: they can survive the harsh cold and vacuum of space for more than a year, they number a tidy five million trillion trillion in number, at least, on planet Earth, and even make up around one in ten cells inside the human body.

And, it turns out, some of them can also see.

Bacterial cells can act as a form of tiny eyeball, enabling bacteria to 'see' their world.
