Being Mortal: Medicine and What Matters in the End

In essence, the idea is to make sure you kick the bucket at the right time, otherwise you have a high risk of getting the ODTAA syndrome (One Damn Thing After Another), some your friends and family members will die before you do, your frail body starts failing in ways you would've never imagined, you have to make tradeoffs that will be hard to endure and sooner or later you will become a burden to your close ones (given you have any) or get sent off to a nursing home where death lingers at every corner. The book is actually about more than that, but this is the most important conclusion I can draw from it at this point.
