I feel like breaking out into a little Loretta Lynn in "Coal Miner's Daughter."

I think to a certain degree that's true but if there are ways to make the job safer they should be explored. In some businesses the competitive nature of the industry tempts many companies to cut corners as it relates to worker safety but in some cases like you say they knew the risk when they took the job.
Occupations like an ocean going fisherman are inherently dangerous and amount of safety gear will overcome fierce weather. We've all watched The Perfect Storm". For fisherman and Alaskan bush pilots it's all about using good judgement and having a healthy respect for the weather and police officers know the bad guys may shoot at them and that's why they have guns too.
Football players do know the risks they're taking and they're well paid to take them but that doesn't mean that a business as wealthy as the NFL can't afford to develop or fund the development of safer headgear for their players. Despite that I wouldn't have any issues with getting bashed around a bit for $400k per year.
I'm getting to that age where a lifetime warranty just doesn't mean as much to me anymore as an afternoon nap.
