Well, when you are really involved in this completely engaging process of creating something new, as this man is, he doesn't have enough attention left over to monitor how his body feels, or his problems at home.
Så, når man er dybt involveret i  denne meget krævende proces, som det at skabe noget nyt, som denne mand er, så har han ikke nok opmærksomhed til overs til at registrere, hvordan hans krop har det, eller hans problemer derhjemme.
