Práve teraz žiariš
The human body constantly emits an extremely faint light, invisible to the eye but detectable with a sensitive camera.

Práve teraz žiariš. Pošli to niekomu, kto tomu neuverí. Tvoje telo vytvára svetlo. Stále. Aj keď si sám v tme so zhasnutými svetlami, trošku žiariš.
To svetlo je veľmi, veľmi slabé. Je tisíckrát slabšie, než dokáže vidieť ľudské oko. Bežné oči si ho preto nikdy nevšimnú. Vedci ale zostrojili špeciálnu kameru. Tá kamera je veľmi citlivá. Dokáže to malé svetlo zachytiť a premeniť na obrázok.
Obrázok ukázal niečo nové. Najviac žiari tvoja tvár a tvoje ruky. Žiara sa počas dňa mení. Najslabšia je ráno a neskôr je silnejšia. Je malá, ale je skutočná. Práve teraz žiariš a ani o tom nevieš.
That's the story.
