Read Jenny Joseph's well loved poem 'When I am old' and embrace your 64 years in the knowledge that you have at least another decade before you can call yourself 'old'. I'm not far behind you (62) and see the next 10 years (if I'm lucky enough to get them) my 'warming up and winding down' to old age decade. And at 72, it's on with the purple and the red hat!
Strangely enough I have developed a penchant for purple (lavender) and red woolly hats. Oh! And cats.
I love that combination of colours... bet you look gorgeous
