"My heart just pounds" [when I stand up and walk 15'] Visiting friends for Thanksgiving and I watched one of them (~280lb non-smoking female in her 50s) GASPING for breath every time she walked to the kitchen to do some dishes or get a pie out of the oven.  As in "I just ran a marathon, hands on knees, gasping for breath".  I asked if she was ok and needed any help and she said "My heart just pounds" while visibly struggling to manage the incredible physical strain of standing up from the couch and walking 15'.     It's so sad, because I'm sitting here thinking to myself "You're going to be dead of a heart attack in five years.  And there's not a thing I can do to stop it as you debate between baking four pies or seven for a Thanksgiving gathering of a whopping 8 people.
