I'm quite enjoying growing older - better than the alternative. I reckon that I'm well on the way to purple hat time and can get away with more outrageous behaviour on the basis of age.
Actually, I'm getting quite excited by the white hair showing through - can't wait for it all to go white - no need for a purple hat then - I'll just use purple dye.
I agree with Bryn - best part of the deal is the grandchildren.
