Can anybody tell me what is wrong with my site: index.htm ?

This is a traffic report on my site alternativehealing.org at about 12:30 a.m.

California time or 3:30 p.m. Singapore time.

You can see that most people who visited this site are from Singapore

(in ratio to the population of different countries.)

If you look at the 2nd chart, the visitors are mostly with graduate school education,

and it does not show any body from no college education and also none with some college.

Another issue is the numbers of visitors have been down.

Can anybody help me to analyze the problems?
