> I will say that now that I am getting older its getting a bit tougher - the pain is worse and lasts longer and real chronic pain kind of bums me out, but I just enjoy the challenge of trying to work around my body.

Please see this as your body trying to tell you something before you end up with a bad injury that could prevent you from running for weeks.

For me, shin splits subsided after I got more comfortable running shoes and shortening the distance covered during runs (i.e. ~5km down to ~3km, 5-days a week).
