As a doctor, I would say why ever bother changing the oil in your Grenadier , it is running perfectly well
I agree ... but ...
when I went the last time to my doctor because I thought I had a problem, he advised me to do a body scan for mapping my body so that they would be able to do an early diagnosis of skin cancer.
Problem: I visited him for a totally different problem.
I didn't do it!
And some ten years ago, after a temporary relationship with a woman, from whom I suspected after stopping the relationship that she had some other "partners" at the same time ...
after 6 months I went to my doctor for aids test and so on, but it was a young doctor who replaced him because of holidays:
and I said "while I am here check for prostate cancer".
She (yes, it was a she) answered, if I remember correctly her words: "I advice you not to do the test. Statistics have shown that the expectation of life is the same with or without cancer treatment for prostate cancer. The difference is: years of treatment and worries!".
I didn't do it.
My father was wrong, he died of cancer less than a year later, but would it have been any different?
Let's be clear: without doctors, I would have been dead a lot of years ago ... intestinal obstruction!
But in the mean time, I know how to solve the "mechanical" problem! Because I had 3 surgeries for the same problem in a time span of 10 years, and after that none anymore (surgeries), but quite a lot of "obstruction" alerts, and some very serious: I know how to solve it. It is a mechanical problem. When I explain it to a doctor, he doesn't believe me!
I believe in doctors.
My comment was like Neil Young says: "It's better to burn out than fade away", can you live with this?
