The Ice Bucket Challenge and ALS: a matter of priorities

Then they suggest that I donate money to the ALS Association . It has been a particularly hot summer, which partly explains the popularity of the phenomenon, and mostly all of these people look adorable soaking wet and spluttering, which is an added bonus.  The ALS Association, and the British version, the Motor Neurone Disease Association, have made boatloads of money off of the challenge.

High blood pressure is a big deal because it increases a person's risk for stroke, heart attack and kidney failure. It is also mostly completely silent, causing no discomfort except at very high levels. The only...
