I&#x27;ve never been a coal miner, but I have worked a number of extremely physically demanding jobs, one especially where people died from poor safety conditions and most of everyone called in sick several days a month ( I was complimented sincerely on what a good worker I was because I only called in sick once per month).<p>any day of that job was much worse than programming when programming on a good day, but programming on a bad day is much worse than any day of that job ever was.
