The four most physically descriptive English words are sick, dead, drunk and fat.
When you hear of an ailing person, for instance, it rocks you, shocks you. There's a gasp of sheer fright at the undertow of life - frailty. Sick is the word that engenders a stark element of guilt/sympathy in people. It's a hell of a lot more vivid and physical than the term healthy. For it's as if we always knew so-and-so was sick, and yet the grim realisation is far more jarring, jilting and disconcerting than any subconscious knowledge of it. And then we realise collectively how defenceless we are.
In the words of Cesar Vallejo, "And man? Poor, poor / He turns his eyes as when a slap on the shoulder summons us / turns his crazed eyes / And everything lived wells up in his look like a pool of guilt."
Dead is all the more physical and vivid, because of its finality and melodramatic, dare I say it, sense of humour. In other words, dead has funnier connotations than sick. At least with death there is relief, release and, in some people's eyes, reprise. It's hard to explain, but there's something so physical about it.
