Sir David Attenborough has confirmed that he won't be returning to Instagram.

The 94-year-old broadcaster and natural historian joined the platform in September – and amassed a million followers in a record time. He shared a series of posts through September and October, but @davidattenborough's bio now reads: "Account no longer active."

Speaking to Greg James on BBC Radio 1 this morning (January 8), Attenborough spoke about his brief stint on social media.

"I'm so old I can’t get used to all these new media but I was persuaded to do so in order to do a message about conservation," he said. "So for a limited period of time I contributed to Instagram but I'm off now. I'm not on it anymore and I don't intend to go back."

Continuing, Attenborough revealed that he has "enough problems" replying to the old-fashioned snail mail he receives. "I get 70 letters a day! I do my very best [to respond to each letter]," he added. "Sometimes people, mercifully, don’t actually put their address on because people are so unaccustomed to sending letters. If you wouldn't mind including a self-addressed stamped envelope I'd be delighted to reply!"

Attenborough has recently been voted the U.K.'s favorite voice – and who could disagree? If you're in the mood to be soothed by his iconic voice, you can watch the brilliant special Attenborough and the Giant Elephant for free (no log-in required) on BBC America here.
