Samson Siasia Celebrates 30th Wedding Anniversary, But he's only 47 years old..meaning?

 

Coach of Nigeria's under 23 football team and former Super Eagles coach and captain, Samson Siasia recently celebrated his 30th wedding anniversary with wife, Eunice. They were treated to a surprise party by the U23 football players recently.
I was surprised that he'd been married for that long and went on his wikipedia to check his age and it says 47. 47 and married for 30 years? Happy wedding anniversary to them...
