#2 Age is just a number
Cristiano Ronaldo will turn 34 in February next year, while Lionel Messi will hit 32 in June - they are ageing. This is one factor which limits every athlete, but to these amazing aliens, it has only been a blessing in disguise.
Everyone was expecting them to decline as they moved into their thirties, but instead, they have only become more mature, adjusting their games to suit their ages, and moving from strength to strength.
Cristiano Ronaldo has turned himself from a flashy winger into a goal scoring machine, while Lionel Messi has thrived off dropping deep into midfield, orchestrating team play, before launching fierce attacks. With these changes, they look set to maintain their levels for some more years.
When even age cannot stop them, what can? Maybe retirement.
