I remember having the distinct opinion (as a teenager) that someone over 25 was OLD and I was certain if they lived to 40 it was pablum from then on. Well ... I have outlived my aging predictions and the only oatmeal in my diet is in cookies.
In fact 46 does not seem old at all to me -- although my body might beg to differ. I have pretty much decided I like myself and I don't get too wrapped around the axle about the age thing. (Check back when I turn 70)
Birthdays are just another reason to eat out and celebrate. Forty Six is going to be a fun year -- I'm looking forward to it.
