In Old Age: A Beginner’s Guide, the author, who was diagnosed with Parkinson’s disease in his forties, reflects on what it’s like to age. His descriptions of the subtle and often unsubtle rebuffs he has received as a result of his disease are both amusing and terrifying, as are the stories of his (mostly positive) interactions with the medical world. His point is that we will all die one day, and that it can be rough to wrap our head around that idea.
The last chapter is focused on societal trends rather than the personal side and I found it meandering and often ill-advised. But I loved everything else about the book.
