Handy Health Hint

Prevent influenza
Wash hand frequently

Yes, but which hand - left or right? Decisions, decisions...

And while we're on the subject of public announcements, who changed the MTR announcements from "This train will terminate at..." to "This train will stop service at..." Unless it's the last train of the day, it is more likely to go back in the opposite direction than to stop service when it reaches the terminus.
