Sir David Attenborough says he is ‘not afraid of death’ as he prepares for 100th birthday

But there is something else that scares him

Ahead of his milestone 100th birthday, the beloved broadcaster and biologist has said he is “not afraid of death”.

As he reflected on his life, he said he is not afraid of dying, bur rather of not living enough.

“I'm not afraid of d.e.a.t.h… I'm afraid of not living enough”, he said.

“After living for nearly a hundred years on this planet, I now understand that the most important place on Earth is not on land but at sea”, he added.

“If we save the sea, we save our world. After a lifetime of filming our planet, I'm sure nothing is more important”, he continued.

The natural historian has previously spoken his fears for growing old, in particular “becoming helpless”.

In his new interview, meanwhile, he has described his career which spans eight decades, as “swanning round the world looking at the most fabulously interesting things”.

Sir David shows no signs of slowing down as he has new shows this year, in spite of worries from fans that he may stop making new programmes.

In a new BBC series, Secret Gardens, he will reveal the hidden worlds and remarkable wildlife thriving within Britain's gardens.

Previously, David Attenborough's 100 Years on Planet Earth was also announced, airing on BBC One and iPlayer.

The celebratory event will feature the BBC Concert Orchestra and special guests, broadcasting live from the Royal Albert Hall on his birthday.
