For example, I distinctly remember an old Washington Post newspaper sitting on a bookshelf from July 21, 1969 with the headline “The Eagle Has Landed – Two Men Walk on the Moon.” Or a fading, brownish-yellow one from August 8, 1974 with the big headline, “Nixon […]

Perhaps no image is more synonymous with the act of wine making than that of a person smushing grapes with their bare feet to extract the precious juices contained therein (in the grapes, not the inevitably sweaty feet).

Few things in childhood are more traumatising than waking up one morning to find your beloved pet fish, Michael Scofield, floating upside down in his tank (true story); his tiny fishy light cruelly extinguished before his time.

Karla S. asks: Why does the week start on Sunday? Why not Wednesday or Friday? As with so many things passed down to us from antiquity, religion is the reason the calendar week starts (for many of us) on Sunday.
