Future in medicine?

Josiah has become quite interested in 'owies' over the past few weeks.  Any mark on his body now requires a bandaid.  For example, I had to reapply not one, not two, but THREE bandaids to a 10 day old "wound" just this morning.  Luckily, I found multicolored bandaids at the Dollar Tree so this new habit isn't costing us $10 for 3 Lightning McQueen bandaids as was previously the case.  Anywho, his concern has now spread beyond his own "health" and on to anyone else who might have a mark on them.  He frequently gets a concerned look on his face, points to a freckle on my arm and asks "You get hurt Mommy?"  And when I try to assure him that no, I am in fact just fine, he shakes his head and states "No Mommy, you hurt"  OK buddy, sure, I'll apply a brightly colored 'noragne' bandaid to my freckle.  Awesome.  The other day when Henry was over for a play date, Josiah noticed that he had a 'wound' on his knee and was very concerned...no need to call CPS, the scrape was at least a week old and almost healed but Josiah thought differently:
