1.  Yes
2.  Yes and no.  I've been trying to eat more non-GMO and more organic foods.  But I also like sweets.  And I imbibe in alcohol, but not daily. 
3.  Positive.  But Mrs. WM might sometimes beg to differ.

I jog 3-4 miles every other day, and then do calisthenics and floor exercises on the other days.  I'm primarily concerned with the cardiovascular health of my body, and I'm not into working out to build visible muscle, obviously. 

The lady is far more health conscious in terms of diet, and has been helping me add kale and spinach to my smoothies.  She's a potent ally of yours Shooey.    But diet is really where I could make the most improvement.

Oh, and I play drums a lot, which actually must be pretty good exercise.  I can jog for 30 minutes and break a slight sweat, and drum for 30 minutes and be completely drenched.

I do resistance training with weights and machines in the gym 4 days a week. I'll swim and do pullups and pushups at the beach the other days.  I disagree with dog and WM on the jogging. Jogging or cycling sucks.   High Intensity Interval Training (HIIT) is better for cardiovascular health than running or cycling. I do sprints or just take a brisk walk on days I don't weight train.   Look at the difference between an Olympic sprinter and a marathon runner. Which one looks better and is in better health? Or just look at this cycler   http://forums.filmnoirbuff.com/viewtopic.php?id=16424
I never jog and my resting heart rate is 50. BTW the man who wrote the book on running, Jim Fixx, died of a heart attack while jogging.

I agree with the Shoo about how easy it is to make excuses but for me I've been doing this so long I feel terrible if I miss a workout. I know a lot of guys like "Bob" in this article.     
http://www.t-nation.com/powerful-words/merry-christmas-bob  I used to smoke and drink, mainly beer, not booze, but I find now, more than an occasional glass or 2 of wine gives me a hangover.

I don't agree with Shoos approach to diet. I follow a high protein, low carb, moderate  fat diet. Love a good grilled cheese burger, no bun. Turkey, chicken, tuna, eggs, cruciferous vegetables like broccoli and good fats like avocado and nuts. I believe fat doesn't make you fat, sugar makes you fat. I'll have a couple servings of whey protein a day in a shake or mixed with greek yogurt or oatmeal. I eat clean most of the time but will have an occasional cheat meal or some pizza or ice cream.

I'm definitely not saying running or jogging is the best exercise.  I know it can also be bad on your feet and joints.  It's just how I choose to stay active.  Ideally I'd like to swim every day.

I will say, I had a physical and blood work done recently, and I was in fine condition.

Good distinction there Dogs, between health and performance.  I don't care about performance one bit, per se.  Just staying active and feeling good is my goal.  I could stand to do some more stretching, as in the past few years I'm not quite as limber as I once was.

So I hear.  Mrs. WM does the stuff.

I'll add that I've made a point of drinking more water throughout the day and I think it's helped.  I can't quite put my finger on the perceived advantage it has imparted, but I just feel a bit healthier.  Keeps things moving right along, flushing the pipes.

With cars.

You'd be a lot worse without it.

There have been a few people in the past few years that have killed themselves by doing stupid "how much water can you drink in 5 minutes bro" challenges.
