Darius lore

Well as I am a Darius main and love the character,who is,yes, brutal at times but also was forced to protect his family and did so very well,despite Draven becoming a cocky bastard. Now I would like to discuss,or rather ask about something which has been bothering me. In the old splash art it was very visable that Darius has gray hair. In the new one it is also visable-the same part of his hair and a small piece of gray hair. Now is the man really that old. I mean does taunt him,however,that does not mean he is that old. Very few characters have their exact age mentioned and the rest is speculation. So I am asking this. Is he really that old-over 50 let's say or more of a 30-35 year old and the gray hair being a result of the hardships he was forced to endure-his parents died,he had to protect his brother and has led several hard battles,which have no doubt exhausted him both physically and mentally....so it's up to you fellow lore geeks to discuss and reach the answer.
