I'm surprised people are still being upset by "Let me google that for you" links when not only is that website rather old, it's also very true that you can take about 3 more seconds out of your day to go to google and look up whatever it is you wanted.
As a matter of fact, I'm fairly certain that you googling Sclerosis would have taken less time than you making a post, asking about what it is and waiting for a response.
Anyways, I'm just glad that there still are people who donate after dumping the ice bucket on their heads. I've never done the challenge, but my sister has.
