I lost my older sister and dad to cancer. I’ve also lost a lot of friends to cancer and my wife and I are getting ready to lose another friend to cancer. And, several years ago, I had some things come up and went through a lot of scans, tests, exams, colonoscopy to make sure it wasn’t the same cancer that my dad had. Once we were all comfortable that I wasn’t in danger of dying any time soon, we quit looking. No treatments. Can you believe it Wrench? They actually let me leave there without a treatment plan! According to you they should have hosed me for thousands of dollars and killed me in the process.
My other reason is that I spend a crap load on insurance. I get two yearly checkups for free. To me, it would be a waste of my money not to get some services out of it. But I also took the time to find a doctor that I really like and trust. He doesn’t come up with a lot of stupid stuff either. He just laughs and says I’m the healthiest fat guy he has ever seen.
But I guess the main reason is that I trust science and I’m not scared of doctors. That’s the two parts you are missing.
