Video lectures are very good. Video easily understood and clear. I love this style of expression, they are addicting people to science.
Wound healing is actually an interesting subject. Both astronauts, who though having a rather low-pressure atmosphere around them to reduce strain on the hull, but have a relatively high amount of oxygen in their breathing air, as well as divers in high-pressure environments report wound healing being sped up several times over normal earth-bound environments. Also in hypnosis there is now a so-called Sichort state after hypnotherapist Walter Sichort, who accidentally discovered it in the 1980s, which allows healing (of broken bones as well) at six to twenty times the rate than when fully conscious. We may be at the threshold of a new era of healing.
