Do i know enough?

Whilst i was doing my last post about Botox, or Botulinum toxin as it is professionally called, i had to do a bit of research. Yes, i don't know everything i will admit it. Now Frankie has had this twice, yet i never really knew all that much about it, i knew it would be beneficial to him, but what else did i know? It would seem not much, the more i researched the more complicated it all became, new words, long long words, some even had numbers, blew my mind a little, then there were new methods of use, and finally the interesting fact that if you are exposed to botox it isn't likely to do to much harm as you become immune over a period of time and the effects of it no longer work, good if you were accidentally exposed to it, not so good for the people that rely on its benefit greatly. My question is, how much do I need to know? Now i am not a doctor, would it be easier if i was, would it be worse? These questions i am unsure on, but for now i will let the doctors do their jobs and i shall do mine, being Frankies Mummy, i know a little of everything and for now that too is alright by me :)
