Ryan and Summer Erickson, of Oakland, are the proud parents of twin boys with one born on Leap Day. Miles was born at 11:58 p.m. Feb. 28 and his brother Walter at 12:09 a.m. Feb. 29 at Alta Bates Summit hospital. ( Pamela Turntine )

It's kind of like one of those word problems in your math class that's something about if a train is going east at 22 mph and the conductor is walking west through the compartments at 3.4 mph, who will win the World Series in 2032? OK, maybe not that bad, but I did have to pull up my calculator for this one.

You've likely heard of the Oakland twins born at Alta Bates Summit Medical Center in Berkeley? Miles Erickson made his debut just before midnight on Feb. 28, and his brother, Walter , came along minutes later on Feb. 29, a.k.a. Leap Day. For every four years Miles ages, Walter will technically age only one. So when Miles is 16, Walter is 4. When Miles is 84, Walter will be (punching it into the calculator now), finally old enough to drink booze. Party at the senior center!
