clearly captivating,had me watching 
BUT there’s always a but,too american maybe.I think for us brit’s DR kevin fong should of started with the every day unsung cardioligist’s in the uk,that are as you read this saving someone’s life through major heart surgery or the cardioangioplasty surgery (thats what i had) and to look at the work being done over here its also amazing.replacing someone’s heart or even a bit of one is i think a long long way off.“hey what do i know” im only a driver 
and they could also explain to any of the heart patient’s about the concoction of drugs you will have to take ( asprin betablockers simvastatins ramipril etc etc depression loss of memory 
.these are the more important .and for me its been two years now.yes the heart is remarkable at what it does.what i know now 
if i could roll back the years would i change anything, you bet i would
