Fitness–Where’s the Oxygen?

My next door neighbor and I have decided we need to get into better shape, feel better during the day, etc.? We went on a little jog this morning at 5:30 a.m.!? I know, David at 5:30 a.m. is pretty crazy!? We started out real well, but we were huffing and puffing before too long.? We made it through and ran and walked for about 30 minutes.? I am pretty sore right now, but thankful that we are getting into shape.? (‘Course I don’t if it will ever be back in shape as I have never really ever been in shape.
