Portuguese striker of Al-Nassr Cristiano Ronaldo confessed why he manages to stay at a high level for a long time.
— Sleep is my main tool. I stick to the times when I should go to bed and when to wake up. For instance, I go to bed around 11 or 12. And I wake up at 8:30. This is my routine. It is probably the most important thing we have in life when it comes to preserving health, — said Cristiano Ronaldo.
