Ray Lewis enjoying retirement by climbing 19,336-foot Mount Kilimanjaro

(USA Today Sports Images)We haven't heard too much from Ray Lewis since he retired after the Super Bowl (though that will change soon), but perhaps it's because he was training to climb the tallest free-standing mountain in the world.

Shuffleboard is apparently not Lewis' retirement thing.
As part of "TackleKili" to raise money and awareness for clean water projects in East Africa, the longtime Ravens linebacker is joining Doug Pitt, actor Brad's brother, and former Bears defensive tackle Tommie Harris among others to climb 19,336-foot Mount Kilimanjaro. The ascent began Wednesday and the group is scheduled to reach the peak on Sunday.

While on the trip, Lewis and the rest of the group has also been helping to fit East African people with hearing aids.

 We probably should have known Lewis wasn't going to sit on his recliner in retirement. And he's giving his energy to a good cause.
