I wear a 33 knot rope on my wrist. When I get a bit slow at work, have a moment of time, or my mind is going idle with odd/evil thoughts, I use it to pray. After lunch I try to pray too. Then I nap. After my evening prayers I use it too. To me, it's a good reminder to keep my thoughts in prayer. If I wear it when I go to Church, I'll use it before Matins/DL begins. During Liturgy, I try to listen and participate as I am able. If I go to a Protestant church, then that thing is turning in my hands the whole service while I ask God to protect my mind and heart from the things being preached.
