Boba is 10 in AOTC. When Obi-Wan found the clones they were cloned 10 years ago.
According to this timeline (
http://en.wikipedia.org/wiki/Star_Wars_Universe_History) Boba was born the same year TFM took place, 32 BBY.
I'm currently reading, Dark Nest I - The Joiner King, which takes place 35 ABY.
Allow me to quote the novel directly.
"I'm tired of getting kicked around by these RePlanetHab pilots. It makes me look old."
"Don't be rediculous," Lea said. "You're barely in your mid sixties."
"That's my point," Han said. "Just because a guy goes a little grey at the temples, people think he's slowing down. They think they can push him around-"
"Han, nobody thinks you're slowing down." Lea's voice grew soft. "You have at least fourty good years left. Maybe even fifty, if you take care of yourself."
A hundred years old and they still call em' good years.
