I'd like to see two things.
- The demographics of people who live within a few miles of golf courses. Are they wealthier with better Healthcare, allowing them to live long enough to develop Alzheimer's?
- Were pesticides used heavily in the golf courses surveyed?
As with all statistics, more data = context.
You tell me obviously, but you just told otterpop that the research material used to validate the other stuff with would be the source.
I don't necessarily disagree with the original point, I'm just pointing this part out.
