Are you suggesting that the human body somehow violates the laws of thermodynamics? Because that would be much stupider than what you seem to be mocking.
No, Slashdot is mostly made up of computer janitors; the greatest insight you'll get out of most of the posters here is, "hurrr durr, the bridge must've been running Windoze! LOL!", with maybe a little "omg the twin towers were collapsed by EXPLOSIVES!!!!"-style conspiracy theory and "THE GOVERNMENT IS BAD!!!" braindead libertarianism thrown in for color.

Clearly, you've not been to the United States in the past ten years. We still make almost all of our non-retail payments with checks here in the financial Third World. My company, for example, still issues checks for expense reimbursement.
You don't even know that there were two presidents named "Roosevelt"? I hope you're not American, because that would be shockingly stupid.
