Unless you’ve been living under a rock for the last few weeks, someone you know or have heard of has poured a bucket of ice water over their head. What started out last year as a challenge between college baseball teammates has snowballed into rather entertaining videos that are popping up all over social media, from A-list celebrities taking part to just about anyone with access to WiFi and a bucket. It’s all for a noble cause, of course. With every frigid pour, 3 more people are nominated to do the same in an effort to raise awareness of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease. It is a disease in which the neurons that control voluntary muscles rapidly degenerate and invariably die.
