I enjoyed your presentation, especially the personal stories at the end. I wonder if moving one of those up to the beginning would capture people's attention more quickly than listing some theoretical issues for later discussion.
Your charts were very helpful. Scatterplots are great storytelling tools! I keep thinking of ways to make them more descriptive (e.g., circles vs. squares for body type), but that wouldn't work as well for a presentation - maybe an article or your book. If you decide to go that direction - let's talk!
Thank you for sharing such a personal issue with us, and for providing the impetus for us to get out and see friends.
