5. Measuring Sleep
Qualitative will have to do:
•Hours slept
•Quality of sleep — scale 1-5
- 5 = great! ... I don’t remember anything
- 4 = occasional waking
- 3 = tossing & turning
- 2 = wandering around the house
- 1 = absolutely awful!
Noticeable difference is what I care about anyway

17. Learnings? 10
1-Leg Standing not having much 9
impact 8
In general ... I sleep fine 7
• I don’t have a sleep “problem” 6
Occasional nights of poor sleep 5
• Perhaps stress related ... perhaps try 4
relaxation techniques
• But, not a major issue 3
Experiment worthwhile anyway
2
• Just to know I don’t have a problem 1
• More self-aware of my sleep habits 0

18. Observations
Difficulty of doing
• Despite reminders
• Finding time — 5 minutes x 3 seems trivial, but it’s not
- Staring into space (boring)
- Reading books (okay), newspaper (tough), screen (can’t)
- TV (great ... but then you’re stuck!)
- Music (good)
- Waiting for tea to steep (best)
Ease & value of self-tracking sleep
• No fancy technology required ... self-observations of sleep quality
sufficient (in this case)
• Moment of reflection — “How did I sleep?” — was a pleasant ritual
