So naturally, I wanted to get more deep sleep for myself and I literally tried almost every gadget, gizmo, device and hack out there -- consumer-grade, clinical-grade, what have you.
Naravno da sam i sam želio što više dubokog sna pa sam doslovno isprobao skoro svaki mogući uređaj i spravicu, one za potrošače, one klinički ispitane, što god želite.
