Funny story....TWO days ago I went running in my neighborhood. I invested in a pair of barefoot running shoes and adopted the toe-heel running style. Mind you, I haven't run since before Mission Year ended and TWO days ago I decided to knock out two miles in my new shoes. Just an FYI: when your calves start hurting like a you-know-what WHILE you're running....that is bad news. TWO days later, I am STILL climbing up and down stairs like the 94 year old women in the church congregation. All I need is the pink cane...
