It is now almost official that opera is good for your heart. As long as there are no frightening bits and you don’t have to run to get there on time, I suppose.
Verdi is apparently the best as the phrasing is just right.
I don’t know what kind of art is best for your heart, but I think some of the sheep on this clip might need some medical attention (e.g. a cholesterol check) before too long. Maybe they are GM.
