You guys that refuse to wear a harness. Do your family a big big favor. Go get more life insurance or accident insurance. One mishap and you could become a parapelegic or a corpse. Why would you not wear a device that could possibly avoid such a tragedy?
Many of you already have life insurance. For what? What's your chances of dying suddenly? You have homeowner's insurance in the event of your house burning down. What's the odds of that happening? Same goes for auto insurance. You pay out hundreds, maybe thousands to prtect you and your family in the event of some tragedy that will most likely never happen.
You go to work and make money. For what? To provide funds for you and your family to live on. Think what they'd live on without that income if you were gone or even worse, in a wheelchair the rest of your life. How long do you think they could sustain their lifestyle on the measley life insurance money?
You have hundred, maybe thousands wrapped up in equipment for your hobbies. Is $100 or so so important that you would jeopardize your families well being? Is five or ten minutes more time getting into a treestand so important? Leave the house 10 minutes earlier.
Buy and wear a harness. They'll be glad you think so much of them. Cemetaries are flush with poor soles that once said "It can't happen to me".
