Keanu Reeves suffered a meltdown when he turned 40.
The 47-year-old actor found it difficult to adjust when he reached the milestone age and admitted he is embarrassed by how he reacted at the time.
He said: ''I had the classic 40 meltdown, I did. It's embarrassing. It was pretty funny. But then I recovered. To me, it was like a second adolescence. Hormonally, my body was changing, my mind was changing, and so my relationship to myself and the world around me came to this assault of finiteness.''
Keanu also found it difficult to come to terms with leaving his youth behind.
He explained: ''It was also the end of the projection of my younger self. I came to the place where I thought, 'I don't know where I am anymore but where have I come from and what am I doing?'''
In addition to coming to terms with his age, the 'Speed' star has also realised he can no longer party like he used to.
When asked if he has a favourite niteclub, he told the Independent newspaper: ''Clubbing? I'm too old for that.''
