Slight deviation from subject, but for what it is worth I made an interesting social discovery recently.
About 15 years ago I made an aviation presentation to a group of mostly Chinese business people. I did not wear glasses and that subject came up in question time, and we noted that nearly all the people in the room apart from myself wore glasses or contacts.
Fast forward to a couple of months ago. Similar group of people, this time I am wearing glasses as I have become an old f**t. I looked around the room and only a couple of them were wearing glasses. What gives?
Lasic. Nearly all of them had been laser treated. I pointed out that as a pilot I am unable to have that process as it is greatly restricted under my licencing authority.
We are now in the wierd situation that you can tell pilots in the room as they are the ones wearing glasses. So the world turns...
