I have an untested theory that anime fans tend to be… by disposition not attached to the physical world. They get by with the education mill and then join the workforce – some of them may do extraordinarily well, some less so. Their level of participation in society at large tends to stop at earning their bread – they are just not the type who get anxious in not participating in the mating rituals, climbing the greasy pole etc. I think it is mostly because their mental life is too occupied with something else better than the real world has to offer. It is not that they are maladjusted – they tend to do this by choice.
