"I just don't see how any one person could play enough to get all those achievements."

My guess is it's easy if you have no life.

Michael, you'd be surprised...

Search video-game related deaths, and Asia is top contender in them.
Death from not taking a break during their 10-15-20 game session in a cafe? Check.
Kid dumps gasoline all over another kid and then lights him on fire, claiming he's a fire mage? Check
Guy kills his friend cause he let him borrow a rare sword in a game, which the friend sold? Check!

I can keep going if you like...

Oh, also, asian kids who play Starcraft can make 400+ actions a minute.

The feats of strength bar is always empty for the same reason you can't view un-obtained feats of strength.
You cant see the un-obtained ones because:
Blizz don't want you to see feats of strength you don't have, whether this is to stop noobs asking WHY CAN'T I GET THIS CHIEV ITS RITE THAR AND ITS IMPOSSIBLE FU BLIZZ FU /wrists or blizz not wanting players to have a list of grayed out achievements that are unachievable.

And you cant see anything on the progress bar because there is no current definite number of feats of strength, as they are revealed when someone gets them.
Or because you cant really progress through them as they are applied retro-actively, most of em anyway.

Ever hear about them dying from malnutrition from playing too much... check.

Think asia's got a problem...

@Michael

I tend to agree with you about a team of people, or at least more than one.

Seems shady, at best
