Happy Birthday to living legend Niki Lauda!

Niki Lauda reaches the big 70 today but that's unlikely to impress the F1 legend and Mercedes non-executive chairman.

It's been a trialing past seven months for the Austrian following the lung transplant he underwent last summer. However, despite the ordeal, this racer's heart hasn't skipped a beat.

Lauda is still hard at work in recovery mode, and while no date has been set for his return to the Mercedes garage, it will hopefully happen sooner rather than later. Go Niki!
