C'mon...
In country like UK, France or Italy, if you're in an emergency condition, you're treated as the emergency recommends. And you will never be denied because of age of "too much" serious condition!
Long lists are created if people want to be examined as periodical checks rather than for a situation. And time goes by because all the people that are in serious conditions come before, as the good sense would recommend.
Valerio,
Thanks for the comments. Compare the age and wait times for hip replacement surgery. I wasn't referring to emergency department admittals, since those are treated by triage and law.
