Third world countries don't have Depression or Diabetes in remotely the numbers that we do because they are busy fighting Malaria and Tuberculosis and sometimes starvation. In fact that's the least divergent prediction.

The more and more insignificant sites popping
up that require login accounts, the more and
more seldon my preferred login names (or any
variant of any of them) are available.

So now regardless of how often I reuse a password
or PIN, whether I can remember the login I chose
for that site is hit/miss.
