Happy birthday! I wish you a healthy and happy life!
I recently followed a course on YouTube by
Yale professor F. Perry Willson, MD MSCE, called Understanding Medical Research: Your Facebook friend is wrong.
Regarding causality, he mentioned the introduction of metal helmets instead of brown cloth caps in the British army in WW 1. After introducting the metal helmets, the War Office was amazed to discover that the incidence of head injuries then increased.
Did the metal helmets cause the head injuries? No.
The number of recorded head injuries increased, but the number of deaths decreased. Previously, if a soldier had been hit on the head by a piece of shrapnel, it would have pierced his cap and probably killed him. This would have been recorded as a death, not a head injury.
I think about this every time I hear someone say that we see disease today that we didn't see in the past. I think the people having these diseases are people who would have died in the past because there was no medical knowledge at the time to keep them alive until they had the opportunity to develop the conditions that seem new or more common today. So hooray medicine!
"Pregnancy is an incredibly risky medical condition. It is 14 TIMES more dangerous than having a safe abortion."
This makes sense intuitively, because I can think of the complications that can occur when giving birth(bleeding out, infectiond sue to water breaking early etc.), but I think that it order to get the message across better I would be a good idea to add a link to something that substantiates this claim.
