Nostalgic click-off time

The word ‘nostalgia‘┬áhas Greek origins (nostos = “homecoming” and algos = “pain, grief, distress,”) but it was coined halfway through the 17th century by a Swiss doctor named Johannes Hofer, who wanted to describe the pain felt by someone who longs to return to his native country (we know it as ‘expats’ homesickness’, I guess.)
