Kui palju inimese keha väärt on, kui arvestada keemiliste elementide hinda?

Kahjuks uuemat arvutust võtta ei ole, seega peame esitlema inimese maksumust 2011. aasta hindades. Keskmiselt koosneb inimese organism 54 erinevast keemilisest elemendist, seega on võetud aluseks 70 kilogrammi kaaluva inimorganismi elementide sisaldus.
- 43 kg hapnikku, hinnaga 129 dollarit,
- 16 kg süsinikku, hinnaga 384 dollarit,
- 7 kilo vesinikku, hinnaga 700 dollarit,
- 1,8 kilo lämmastikku, hinnaga 7,2 dollarit,
- üks kilo kaltsiumi, hinnaga 200 dollarit.
- jne
Kõige kallim element meie kehas paistab olevat kuld, aga seda on siiski vaid ühe sendi eest. Raud meie kehas ei maksa niigi palju.
Niisiis, 2011. aasta hindades maksis meie keha 1985 dollarit ja 77 senti. Kas ja kui palju elementide hinnad vahepeal muutunud, me ei hakka praegu arvutama, kuid inflatsiooni sisse arvestades oleks me hind täna 2099,35 dollarit ehk 1875,45 eurot.
Võrdluseks üks teine meie keha elementide hinnatabel, arvestatud küll 76-kilose kehaga. Tundub, et mõned numbrid ka lahknevad eelnenud arvutusest. Eks igaüks võib hinna oma kehakaalu kohta ümber arvutada:
