Careful... it's a little too easy to ascribe things like that to a superficial cultural trait. English has a huge variety of terms for extreme tiredness: whacked, bushed, wiped out, worn out, drained, burned out, beat, knackered, fried, shattered, frazzled, zonked... must be the puritan work ethic or something. We've even got a few onomatopoeia of our own: feeling kinda.. ugh.. meh... bleugh... I mean, whew, yeesh. Just... phew. Maybe being tired is just the global human condition.
