No one is immune to watching that social media dial move up - not even the former Chief Rabbi.

Rabbi Lord Sacks tweeted earlier today that his TED talk video has hit 1.5 million views.

Thank you to everyone who has watched & shared my @TEDTalks in recent months. Just passed 1.5M views. 😄 Please keep spreading its message - still very much needed as we enter #2018. Watch or read the talk here: https://t.co/jA3OFm8yXa. pic.twitter.com/3F57ii3B5A

His video, called How we can face the future, together, poses the question: "Is there something we can do, each of us, to be able to face the future without fear?" and proposes solutions to dealing with religious intolerance. This is a message, he said, that is "still very much needed as we enter 2018".
