Why should you get to know 73goingon55?

I'm told I'm good looking and nobody believes me when I tell them my age.I behave much younger than my years. I have a great sense of fun and laughter is the spice of life. Science rather than art based education but that does'nt mean I'm turned off by arty things. I used to paint quite well and was a lead singer in the local operatic society. I like deep discussion on any topic from politics to philosophy, but always with an underlying sense of humour.I'm generous, sentimental and affectionate.
I like driving and fast cars and sailing in Norfolk is a passion as you'll see from one of my photo's. Game to do or try pretty well anything that's interesting and stimulating and with the right person. I love open spaces and live in a semi rural wooded location with two acres of grounds.
I know I'm unusual,a one off, but if you are bright and a free spirit you're the one for me.
Don't be put off by my age until you get to talk to me, or meet me. I'm going to live another twenty five years until I'm at least eighty.
Not great pics., but I'm usually behind the camera.
.....a new addition to my profile:- I'd give up smoking if the right girl came along.

He describes his ideal match thus:

Bright intelligent but not stuffy.
Attractive enough to give me feel good factor when we are together.Should like the outdoors (eg sailing)but not averse to curling up in an armchair and watching a good film or documentary on TV.( no soaps please)
She should have a good sense of fun and take a joke with a genuine laugh.
She'll be modern in outlook, forward thinking and dresses well.But casual is fine too.
She should be sexy, but not overtly so.
On a perfect date we would both know instinctively if we wanted to meet again.
So are you this paragon of most virtues?
