Those are examples of bad luck deaths. A dumb death would be something like Steve Jobs' demise. Here's a very wealthy guy who could have had any available treatment for his problem but ignored warning signs and then sought experimental treatments that delayed the proper procedures until it was too late for what he needed. We'll never know how much longer he could have survived had he pursued more conventional treatment earlier and that's a shame for us he played dumb in the biggest predictament anyone can face.
Despite all of life's bumps and bruises, I'm still committed to making this world better one smile, one laugh at a time, every day!
