I ask myself every time. I don't just try to put my finger through my hand either. I try to become really aware of my body, how I feel and what's going on around me. I've had like 10 people ask me about LDing in the past 2 days and on top of that have been thinking about it almost constantly with the MILD class and all. Whenever I have a thought about LDing I usually do one. I don't even always do them in LDs, it's just sort of another thing I can do to put my mind on it.
