Aging parents

Tan Sri & Puan Sri (for those who are not in the know, these are Malaysian titles bestowed by the King of Malaysia, they are equivalent to Lord & Lady in the UK.) 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 holistic pharmacy. 

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

My sister and I have/had more successful careers but 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.
