Hashtags usually take the backing of a few big names to gain popularity, so it was good news for #IKnewIWasOld when someone with almost 13 million followers began relentlessly tweeting it.
That someone was Neil deGrasse Tyson, American astronomer and science communicator, who used his 60th birthday to really get behind the sentiment of the hashtag with no fewer than 22 tweets on the subject.
From birthdays to bedtime, the 60-year-old covered it all.

The irony being of course that Tyson demonstrated an ability to understand social media unlike most 60-year-old people during his tweet storm.
Twitter users were certainly impressed with Tyson's insights:
