Formula 1 race winner Rubens Barrichello has praised Fernando Alonso's ability to keep performing at the 'highest level' in F1, while also revealing his plans to continue his own racing career, despite being 51.
Barrichello raced in F1 from 1993-2011, claiming 11 race victories and forming an iconic partnership with seven-time world champion Michael Schumacher at Ferrari.
Now, Barrichello has pointed to Alonso's success as a way of justifying his desire to continue racing long into his 50s.
"How can it be that Alonso continues at the highest level at 42 years old? In the end, it's all within us," he told Mundo Deportivo.
"It's not outside, not in what you talk about or in anything. It's what we like to do. I really love, love piloting.
"Surely, when you go from 40 to 50, the physical part... the eyes... you start to have a little more problems. But the mental part and all the exercises that I have been doing for so many years can be maintained over time.
"I am very well trained to continue doing it for many more years."
