Is it possible to live Better?

Yes! but don't think there is a universal answer for this and also this question cannot be answered in one post but the idea is certainly worth pursuing. 

To me it looks like It all depends on our of reference

• Mr Pedro is 87 years old, wakes up every morning at 3 and have his first glass of wine and no coffee.  Around 9-10 when the day started to heat up he would switch over to Beer. In the afternoon he would start to sip brandy and coke till sundown. Between 7 & 8 he is in bed. His greatest joy was to supply neighbours and everyone that come around to visit with bags full of vegetables from his own garden which he maintained alone. 
• Mr Harley goes for a swim every morning winter and summer. Spends the rest of his day reading no other exercises.
• Bronwyn spends most of her time with religious activities  swim a easy 1000 meter early morning. Her ID card says she is 80 something but she has a body of a 30 something and a personality of youngster.  When she talks about the Higher Power she absolutely glows 

Living Better at a later stage in ones life all just luck or just mindset - is there actually something you can to prepare.

Once you reach the otherside of Fifty life will start to look a bit different and you will realize that thing that you to do is now taking a little bit more effort to complete. 

The nice about this whole realization is that one can make adjustments

• Early morning brain-freeze-swim is mind blowing. 
• Going for early morning drives 
• Watching the sun coming up is a never-ending-experience

When you are on the otherside one also realize that

• watching Television is not adding any value to your quality of life, it is actually steeling the limited time you have left to add. . . . Maybe if you should take your camera/cellphone and start snaping the ants working inside the garden/kitchen. Documenting things in your space might make you more aware of the great things around you.
  

Somethings one can change but others you cannot, just accept the mistakes that was made . Don't live in regret - get into you swimming suit and enter the water.

See you on the otherside
