What is a Cystometry/Cystometrogram (CMG)? Cystometry, or cystometrogram, with a pressure flow study is part of urodynamic testing (or UDS). These tests measure how well the bladder functions. They help diagnose problems related to urine control. These can be incontinence, difficulty emptying the bladder, overactive bladder, obstructions or frequent infections. Cystometry is used to measure how much urine the bladder can hold.
Tums - Expiration Date. I got a large package of Tums at a discount store for a really good price, but didn't notice the expiration date until later. They are marked June 2004 - I'd throw them out, but I remember my former boss who used to work at a pharmacy told me that asprin usually lasts much longer than its expiration date.
Cookie Expiration. Every time a hit is sent to Google Analytics, the cookie expiration time is updated to be the current time plus the value of the cookieExpires field. This means that if you use the default cookieExpires time of two years, and a user visits your site every month, their cookie will never expire.
