I work on the machines that process mail for the USPS. Letters start at the feeder and within 1 foot of travel are moving at 20 mph, there is stress on the envelope. The mailpiece is routed around a series of turns to kill time while the optics read the mailpiece and determine sortation.

The mailpiece is then routed to a pocket where it goes from 20mph to zero with a quarter inch foam bumper to stop it. This machine processes at about 40,000 pieces an hour.

Writing "fragile" on an envelope is a false hope. Mailpieces go through the system without the human eye even looking at them until the carrier puts it in your mailbox.

If you want a fragile piece to go manual, then box it and pay the extra postage. The video and game rental industry companies need to build a better mailpiece to protect their content.

I'm not sure anyone will read this deep but I'll post anyway...

If the "relief" from drinking caffiene is coming 8-10 minutes after drinking... that is a psychosematic reaction ( psychological addiction vs physical addiction), your body doesn't get the caffiene for at least a half hour.

So I suggest you move to a blended coffee first cutting the caffiene in half, then in half again after a while until you reach the level you want.
