Nothing like cutting your last piece of crown for a room a 1/2" short, then having to spend 1/2 a day or more searching out a single piece!
I think by the time my kids, definitely my grand kids(none yet), are grown this will come to pass for all the organs and/or limbs. The best thing is not dealing with the rejection from transplants for organs.
Seems like science fiction always comes to pass as reality.
