Not really...
I had a cousin born in a leap year and he would be 20 today while I am 80.
(That didn’t stop him from going in the Navy at 4 1/2. <: <: <:)
Yes, really.
Aside from the fact that your post is a non sequitur, saying "Feb. 29 in a leap year" is like saying "5 AM in the morning."
Redundant
