^ True enough. I don't know if it's the same survey but apparently these results were obtained by asking children questions, which to me, isn't a great way of obtaining this information, even if it seems the most sensible. Children don't know the exact details of everything they do (you try asking a kid if they suffer from depression and see what type of answer you get), and the answers they have given could be forced in some way. I know when I was about 8 I got a questionnaire asking about my family life, exercise and so forth, but I didn't care, I just completed it as quick as I could.
