I'm a blood-donor (yay me!), but would prefer not to have to be.
How close are we to manufacturing blood - so that we don't have to prod people with needles - or some other leap forward with in this line of science?
What innovations have been made recently or are on the verge of creation?

Interestingly, artificial blood has been around for some time. The NIH has a few items on this, with some pretty good information on artificial blood.


There have been some pretty epic breakthroughs using pluripotent stem cells to "mass produce" O-type red blood cells, but these are still in trial stages. It's definitely something that scientists are working on and of great importance, as 5 million Americans and many millions more internationally require blood transfusions per year.

From what I know so far, we have come close. Here is a link which you may find interesting.

Is that true?! I had to be put under when i had my wisdom teeth out because I have a REALLY good flight reflex and my dentist was like NOPE. :ROFLMAO: :innocent:

Chewing gum will lessen the flight & fight tendency but I wouldn't think so when extracting wisdom teeth. I'd be flying out of the dental chair with you . . . I'd be opting to go under myself :)

But yes, it is true about chewing gum . . .

That's really interesting. I'm guessing that has something to do with ancient mammal heritage - that our species felt safest when eating something, probably in a group which, in fact, a dentist chair resembles.
 
Question is if you get blood from a person and blood is energy. Would you develop habits of that person from having their blood. I know that tends to happen with patients that get a new heart from somebody. You somehow retain some of their energy.
