Mark Zuckerberg challenged Bill Gates to dump a bucket of ice water on his head to raise awareness for ALS.
Amyotrophic lateral sclerosis (ALS) — also referred to as motor neurone disease (MND), Charcot disease, and, in the United States, Lou Gehrig’s disease—is a neurodegenerative disease with various causes. It is characterised by muscle spasticity, rapidly progressive weakness due to muscle atrophy, difficulty in speaking (dysarthria), swallowing (dysphagia), and breathing (dyspnea). ALS is the most common of the five motor neuron diseases. (Source: Wikipedia)
And yes, Bill Gates is always up for a challenge! He shared the challenge video on his facebook page where he also passed in on to On Air with Ryan Seacrest, Chris Anderson from TED, and Elon Musk. Interestingly, Mark Zukerberg commented “That’s definitely a better design. Well done.” Have a look at the video below. 🙂
