Heart surgery scar tattoo idea

Hello!

I have a heart surgery scar from childhood the goes down my chest almost to my belly button. I was thinking about getting the staff of Asclepius tattooed on it with the staff being the scar and then the snake winding around it. I'm going to be going to medical school this year or next year and my scar as been my key motivation to become a doctor since childhood. Just wanted some advice if this is a good idea and some ideas of what to maybe add to make it more meaningful/interesting. Any ideas are welcome and this would be my first tattoo ever. Thank You!
