Star Trek was about characters being philosophical and exploring the human condition, using science that was credible - a criteria established by Roddenberry at the onset of the franchise, and solving issues through diplomacy and negotiation, and occasionally, with weapons.

As I mentioned in a previous thread, a friend's partner is in a world clinical trial at the moment, one of only six or eight people having special blood serum treatment on a ligament that had previously refused to repair itself. A large amount of blood was taken, reduced down to a small amount of serum, injected back into the problem site - and the ligament has been given a boost for the body to start repairing itself.
