Did it ever happen to you to practice some activities and feel so absorbed by it to lose the sense of time?

My friends asked me how I could stay in the sun for so long. Only two hours before I was complaining about the heat and how this took away the forces, then, as if by magic, I had forgotten the hardships, the moans, the tiredness!
