Sleep, health, and random stuff

I seem to be getting back to my 6 hour per night sleep pattern. I'm sure if I went back to bed at my natural wake up time I could easily get another full 90 minute cycle, but I've been getting up and making coffee to get the day started. I will admit to taking a brief nap at some point in the late afternoon or evening. 
It works.

I feel fortunate to be a good sleeper when I know that many people have a difficult time sleeping well. I think that a good night's sleep is a vital part of good health. Admittedly, I haven't always thought that way. Typically, I go to bed between midnight and 1 am, and get up between 6 and 7 or whenever I've finished sleeping for the night. I tend to fall asleep quickly and also wake up easily. 
People have asked if I am more of a morning person or night person. I am usually just awake and have no real preference. 
I started getting a little bit of exercise recently(walking or exercise cycle), and have noticed that I sleep more soundly on days that I have exercised, even if the exercise is earlier in the day.

I had my annual physical yesterday and it turns out that I am pretty healthy for a fat guy. The Doc reminded me that there are no real health benefits from smoking cigars and drinking alcohol (even in moderation), and there can definitely be negative consequences.
I have cut back on both, but will probably continue to indulge in the occasional sip and smoke afternoons on the deck that seem to soothe my soul.  
He did not suggest cutting out my daily coffee, but did suggest being aware of my caffeine intake and how it can affect blood pressure, anxiety, sleep, and other aspects of health.

In a strange juxtaposition, retirement has found me being more attentive to my mental and spiritual well being and less concerned with my physical care. I think our Western culture is more the opposite way. I need to find a better balance.
It is interesting that we have doctors to care for our physical well being, but tend to shun the practices and practitioners of mental care that many other cultures embrace.

So, I'm curious...
Do you sleep well or struggle to get a good night's rest?
Do you have a nighttime ritual to help you sleep better?
How does diet impact your sleep quality?
Do you reduce your sleep time to make time for awake activities?
Do you consider good sleep to be a vital part of good health?
Are you willing to make changes to your awake time to allow for better sleep?

I am truly interested to hear what different perceptions people have about sleep.
My -- I'll sleep when I'm dead -- perspective has definitely changed even though I am still pretty much a short sleeper.
