The scar was at least twenty years old. It was already in a ‘healed’ state as far as most people count healing. This event is called ‘retracing’. In effect the body recreates the damage, and then restructures the tissue for a much higher level of healing.
Actually, my skin now as if the burn never happened. I have photographic evidence, which obviously will only be use to me, as it just looks like a fresh scar. It looked and FELT like it had just freshly been burned, but the burn event was at least 20 years earlier. And now there is no sign of a burn ever happening.
That is much easier to explain. Most people experience just the regular scaring as ‘healing’ for a traumatic event, as regular nutrition, and biological energetics is generally too low to permit a complete healing. But if one ever has some sustained improved nutritional input, retracing may occur. I am sure there is some thresh hold which must be achieved, and that is difficult to determine for every person.
