Once again you show your ignorance and your willingness to flap your gums about something you obviously know little about.
I made a general statement that no one can be absolutely certain about anything in medicine. The recent story of the guy who was in a coma for years only to regain his mental faculties is a case in point. But that case is the exception not the rule.
Then I said it was common in medicine to make such statements as to survivability based on the techniques or treatment modality used. Those educated estimates are based on facts garnered from previous cases and are frequently used to determine course of actions with regard to treatment. But, to get back to your juvenile and ill-informed name calling about the practice, let me give you an example that should be clearly evident, even to you.
The first successful heart transplant occurred 12/3/1967. So, a patient with restrictive cardiomyopathy has a successful heart transplant performed in 1970. Therefore, a statement that "five years ago that patient would not have survived" would have been accurate. I know that example is a little simplistic, but considering your level of reasoning and background in medicine, I thought it would illustrate how wrong you are in a manner you would be most capable of understanding.
Your ignorance to my background is comedic.
I know that you want to get the last word in every disagreement that you're involved in so you can go ahead.
The bottom line is that no one can make any "certain" statements as far as medicine goes.
How did the medical world discover that electrical impulses moved muscles?
How was the pacemaker invented?
How was nitrous oxide introduced as a key to painless surgery?
How did doctors discover to inject dye into the right coronary artery when they needed to take a contrasted image?
How was insulin discovered?
Do some research before you flap your jaws.
Ok, because I know you're too prideful to research these questions, I'll give you the answer.
All of these medical breakthroughs were discovered by accident.
That's right, medicine is not an exact science.
Go ahead and rebut anything you want, I'm done educating you.
