What makes you lose track of time?

my Stepmom gave me some topics to journal to when I went to visit her and my Dad today. She received these game cards

which have really reflective and inspiring conceptual questions to them. She gave me 7 cards out of the deck, one for each day of the coming

week. So the first question/card is: "What makes you lose track of time?"

I will look at this question in the spirit of 'what activity' - for me -, my illness can make me spin mentally for hours and hours and I do lose track of time whilst sitting in front of the TV - and yet I think I want to focus on, what kind of work and activity as I said above. What kind of thing gives me a sense of flow and harmony.

I think for me when I work at the market and I am just busy putting things together as 'my part' of the team in my section - and helping people - there's such a sense of flow about that. 
I also, once I get started, have that experience with my new yoga class. It's hard work and sometimes I can't wait till it's over - but then also - the time goes by so quickly.

I also am thinking about moving on to something quite different in my life. I am not so religious - but I do like the solemnity and the spirit of the religious life - my friend is the Abbess of a monastery, and I feel myself drawn to go

and live there with her - helping the whole family of sisters and brothers run the place. Perhaps it's that common purpose nature of it that really draws me in. Anyways, this is what I am thinking about for now.
