Nostalgia

According to Wikipedia nostalgia has a history of meaning something in medical terms: Greek roots (νόστος = nostos = returning home, and άλγος = algos = pain/longing)to refer to "the pain a sick person feels because he wishes to return to his native land, and fears never to see it again".

But boy, when I look at pictures of myself 10 years ago, all I wish for is that ass and that body. Woohoo I was SMOKIN' hot! Good thing there is also trying to relive one's youth...or recapture it...or work back towards it?
