It's called getting old my friend .. *L*
I remember years ago, when I was pregnant with Dana and I was sitting on the floor (indian style) playing with Jessie at the Dr. office .. when it was our turn to see the doctor, I just popped up and started walking, and I remember the nurse commenting on how in the world could I do that ..
NOW ... many years later .. I understand what she meant .. I can't do that anymore ..LOL
