Goro is an ADCOM, and he knows better, but if you have the space I would say include it! Now it depends how you put it also. I am thinking of putting it more along the lines of - "Oh I explored other aspects of medicine too 1) to rule out other med careers. 2) just to increase my knowledge about how different professions of medical field come together." etc.
But yes your 105 physician shadowing hours are great by itself.
