Don't fall down the stairs. You can break your shoulder bone in the more sentient of your arms. It's not only somewhat painful, but also leaves you with the pecking/typing ability of five fingers which are sinister.
In other words, my posts will be short until I learn single-hand typing superpowers.
The silver lining in this cloud is a chance to do real research on health care costs. For example, the shoulder immobilizer the ER gave me will cost either me or the insurer between 63 and 110 dollars. Identical (or better) are for sale online for less than 30 dollars. This may reflect the markup pricing hospitals practice.
