What can potentially affect the heart?

Answer 1

There are many things that can affect the heart.

Even living "too" healthy can sometimes affect the heart. such as running too much, over exercising, and much more.

Of course living bad also affects the heart. Such as eating fast food, greasy food, smoking, doing drugs, etc.

We are realizing with science that almost everything is bad for you these days.

So the trick is to do healthy stuff but in moderation.
