re: why is no one saying "Lou Gehrig's Disease" anymore?

We've become more medically knowledgeable. I think people are more comfortable using the actual terms (although this is an acronym). Plus people are living longer in general so the disease has more time to rear its ugly head without being hidden by other ailments or causes of death. This has increased the diagnosis rate and its become a lot more people's disease.....not just Lou Gherig's.
