That's a lot of drastic change. I get that a heart attack can change your perspective on life and mortality, but you might want to address what you see as wrong with your life one variable at a time, rather than all at once. Baby, bathwater, and all that.

Congratulations on the change, if it's for the best, it's worth it.
But I also agree with Koshchei.
And don't get this the wrong way, but that heart attack didn't develop last year.
Stress could made it happen now, but it was all those years before that caused it.
I'm just saying to be careful and change life habits. Eating habits, make sure you make exercise, etc., etc..
Those clogged arteries weren't caused by your (former) new job.
is DEEP.
