Hérita N'Kongolo Ilunga

According to Wikipedia, Hérita N'Kongolo Ilunga was born in Kinshasa on 25th February 1982. I wonder if the Congo record births of its citizens? Rumour has it he is really 38 rather than 28 years old. I must say, that since he signed his four year contract with West Ham in April 2009 he looks and plays like someone at the very end of their career. One wag has suggested he should be carbon dated? Is it possible to work out accurately how old someone is?
