I found out last week or so that MSN Encarta is closing down. This morning, they have a list of 10 pointless things in the 21st century, and I can't say I agree with some of it.
Item 10: Ties serve a purpose; they started out as a lady's kerchief, that her champion knight would wear round his neck as he defended her honour. The 16th century ruff did have a purpose; they hid the scars, left on someone's skin if they were suffering from syphilis. That's a sexually transmitted disease with some very nasty symptoms.
