He may be 80-years-old, and more than eligible for his bus pass, but we'd say Karl Lagerfeld easily has more energy than a teenager.
Not only does the fashion designer still oversee three major fashion houses – Chanel, Fendi, and his own eponymous label – but he continues to shoot his own campaigns, open new stores and recently announced plans to design a hotel. Phew.
So how does he continue to operate like a twentysomething? It's all down to who you're mates with. Mr Lagerfeld credits having young friends – and steering clear of his peers – for his youthfulness.
'I don't know anyone from my generation. I find those people terrible,' he says. 'Even younger people are starting to talk about circulation problems. I have extreme self discipline, which I can barely call self discipline anymore because I can't see any other way to be,' the designer told Zeit.de.
And what about maintaing a youthful look? 'Nothing makes you look older than attempting to look young,' he said.
'You can fool anyone, apart from the young. The worst are the lip operations. There are people who have it done and I don't recognise them afterwards. They look like they flew through the windscreen during a car accident and were patched up badly afterwards.'
Well, that's told us then...
