It usually does that to people, but being here with a similar group should help you see this just a bit of plumbing that needs attention on occasion, and we go on leading normal lives with minor adjustments. Most of my adjustments have been age related.
PS: I feel that much of this problem is centered around the mistaken view (pervasive in our language) that the heart is special.
- affairs of the heart
- the heart of the matter
- my heart isn't in it anymore
stuff like that.
Yet the brain is often maligned in language as only being about intelligence or emotion:
- he's some sort of brainiac
- doesn't have a brain
- all those egg heads
However the heart is no more than a pump. Sure you can't live without a heart, but equally you can't live without a liver or a brain. Certainly its crucial but can be repaired or even replaced (see heart lung transplants). However disease like cancer seldom strikes the heart but does indeed strike the brain and if it does you're a goner ...
Repair of the heart is (while a complex surgery) possible. The brain ... not so much.
