Medical Mondays: Chain of Factoids
Oh, the human body. So fragile and yet so tough.
Let's review some factoids about the amazing human body and exercise a little tangential thinking.
You make about one liter of spit a day. Over a lifetime, that's about one Olympic sized swimming pool. Don't think Michael Phelps would want to swim in that.
Most humans height is equal to the length from their fingertip to fingertip. Except Michael Phelps, whose wingspan is four inches longer than his height.
Speaking of length, the total length of all your blood vessels lines up is around 60,000 miles (though I've read up to 100,000 miles). That's a few trips around the equator!
But let's get two dimensional. The total surface area of your lungs, if laid out flat, would be about the size of half a tennis court. (I'm having visions of lung smeared courts, so let's move on.)
You only need one lung to survive. Actually, you can also live without one kidney, most of your liver, your spleen, your stomach, and many feet of intestine, and of course, your limbs. Talk about traveling light. Sure, you might feel pretty awful, but...
What if you want them back, cyborg style? You can have a cochlear implant (for hearing); an artificial heart; dialysis to replace the kidneys; digital interface placed on your retina (or just a non-functioning replacement eyeball); a deep brain stimulator for depression, epilepsy, or Parkinson's disease; penile implants; and artificial limbs, not to mention the metal plates and bars used to fix broken bones. Using stem cells or tissues, there are also possibilities for replacement pancreas, trachea, bladders, liver, skin and of course, donated organs...the list goes on!
For more factoids to stun your friends, here's a fun list:

All I ask is that you become a follower and post a link on your blog when I post your answer. This is for fictional scenarios, only. Please check out the boring but necessary disclaimer on my sidebar --> Also, don't forget to stop by Laura Diamond's Mental Health Mondays and Sarah Fine's The Strangest Situation for great psychiatric and psychological viewpoints on all things literary. :)
Also, there are a few days left for my GIVE ONE/DONATE ONE book giveaway, so comment if you'd like to win!
And one last thing: Sarah Fine is being interviewed on her favorite sci-fi books and *gulp* CONTROL is on the list!
