I only got to about a minute before my internet started crapping out and I'm waiting for the buffer to fill up enough to continue...
However already I have something to add to the conversation.
Between 1990 and 2010 I went to the doctor's office twice. One after being hit by a car, and once again years later when I noticed my eyesight was getting worse.
Nearing the end of 2010 I wasn't feeling too well, but I sucked it up and got better. Then for the next 6 months I kept getting sick and getting better, never bothering to go see a doctor (despite my friends telling me to do so). By July 2011 I finally relented and went to see my family doctor, a month later I was hospitalised and getting chemo treatments for stage IV Hodgekins Lymphoma. I'm doing fine now, but a whole lot of treatment (chemo and radiation and more chemo, and a stem-cell transplant) could have been avoided if I had gone and went to my doctor earlier.
So, morale of the story, don't just tough it out...
