It looks like James Gandolfini died the same way my dad did - a heart attack in his fifties. Dad wasn't as big of a guy, and he ate fairly well and played sports. That's not enough when there could be hidden hardening arteries, long term stress from sleep apnea or problems swallowing, slightly elevated cholesterol.
I lost my dad 14 years ago this week; every June I go through a bout of depression. I guess I just want to say I hope all of you never go through this horror.
