Aging parents

Tan Sri & Puan Sri (for those who are not in the know, those titles are equivalent to Lord & Lady) will be hitting their 70's very soon. How do you age gracefully? 

For my parents, they've been spending a lot of time in this particular clinic in Switzerland called The Paracelsus clinic. http://www.drrausway.com Stem cells injected here & there. Came back with an entire pharmacy. 

They also bought out the penthouse next door for my brother & family.

My sister and I have/had far more successful careers. My brother is dependent on my Dad for contracts, recommendations, business, etc. 

This is sad. Not a lot of time left with my parents. And THIS is the way it is.
