I think the most important thing in life, besides live it with all your heart, is balance.
Have a healthy diet is very important, exercise , all your recommendations are correct.
But balance will help you to enjoy every minute of your life, and when the times comes, accept the natural end of it.
I agree with you
Daily Exercise is very important if one must live long
Yes, indeed. At least 3 times a week if you're too busy.
30 min and you are done with yourself.
