I apparently have good genes for longevity, but I doubt they have much to do with autism. Mom's side, without the Aspie DNA, lives longest and has a health span that is most closely in line with lifespan.
I agree with the comments on stress. My relationship with life is complicated. I love food, music and dancing, a glass of good beer or coffee, a chance to wander city streets. The smell of old books, the taste of apple cider, the weight of my leather duster, the kisses of the man I love, the and the sheen of brass all conspire to make me love life. That said, living in this world is like walking around in shoes half a size too small. The stress is constant.
I never sleep and work incessantly. My specific interest is tuba, which is the most efficient way to give one's self a bad back. It has torn up my knees and given me a bit of nerve damage in both shoulders and one of my hands along with some interesting scars. Does anyone else have a special interest they think will be the death of them? At eighteen, my face is already lined. There is a bit of gray in my hair.
Stress may shorten our lives. Some of us may self-medicate with damaging substances to deal with that. Isolation is probably unhealthy. Many of us are poor because of difficulties holding down jobs. In America, that may continue to make healthcare a problem for some time to come. Not all of our interests are good for us. We tend not to notice minor aches and pains that could signify larger problems and might send NTs to their doctors. If anything, we probably live shorter lives.

But, ah, my foes and oh, my friends--
It gives a lovely light!"
