Today should be a reminder as to why people like Nico Rosberg made the decisions they did regarding their sporting career. They're away for so long every year that the personal sacrifices mount and mount until a hard decision has to be made - what to separate from.

Nico had his World Championship and proved all he felt he needed to, so it made sense to spend more time with his family and not risk his health. Valtteri and others who've had to make these decisions have things to prove and win yet in their careers.

It's gutting and also a showing of what drivers have to sacrifice when they're a part of F1. Not only them - managers, staff, they all have to go through spending so much time away their personal lives and relationships are put under strain. My heart breaks for all of them.
