So what happens to all of the valves we possess in the arteries and viens throughout our body, which prevent blood from flowing backwards...? They work/are formed from the constant rythm of the heart beating. Now you put an impeller pump in and the valves wouln't have a chance to close (or very seldom). Depending on whatever stress is placed on the body (like standing on your head), all those little valves that have weakened from non-use might cause problems... just a thought.
Again, it would not be necessary. Yes, these valves exist for a good reason in our current bodies. They exist to prevent a reverse in pressure, which would blow up your heart. You no longer have a heart beat, but a constant linear (ie. non-rhythmic) flow of fluids. No contraction and expansion rhythm means no need for one-way valves.
Excellent argument! I can understand what you are saying.. But this is sad news.. Take for example when you are scared your heart races.. when you're excited your heart races.. when you lay still and your heart comes to rest you feel tired and fall asleep. So, by what you are saying a heart that flows at a consistant rate should make you a very dull person. So, we are turning ourselves into robots?...
Yes, I cannot argue. Circadian rhythm, biological function, and strong emotional response do not lend themselves well to mechanical systems. These biological functions will suffer, but I think the lack of death will be enough of a psycological benefit to prevent too much negative reaction to the changes that need to be made.
We give up too much of what traditionally "makes us human" as it is. Eight hours of sleep 100 years ago was a rarity, because most people got substantially more. Artificial lighting allows humans to work well into the dead of night, beyond the point where we would normally not be able to function due to a lack of proper lighting. Any surgeries and modern medicine extend lives beyond what we could biologically deal with. All of this is true, but is often overlooked because it is common in modern contexts. How we adapt to something new defines humanity better than any other currently known species. Live and change, or die; this is the impetus of evolution for a very good reason.
Philosophy aside, consider this a thought exercise at best. People generally do not accept something so alien as a component of their bodies. Limited vision is a problem, but it also prevents people from grafting a gun into their arms for giggles. Though that does seem pretty awesome as I say it....
