Just wondering about your time schedule for healing. What I'm getting at is that the eyeball can heal 3-4 layers of damaged cornea in about 1-2 days. That's quick for a soft tissue to repair itself.
On the other hand, if a bone, which has a much greater molecular density, can heal in 6-8 weeks, why can't the softer tissue-organs heal in about 1-2 weeks?
Just trying to use 'deductive reasoning' to figure out if you're really accurate in your assessment of Charlie's abilities or not. I mean, if the tonics can set up the optimum nutritional/healing conditions, then maybe we should re-figure the validity of his tonics.
