Since you're getting older you should be taking time to appreciate the finer things in life. Have you ever regretted your lack of knowledge of classical music? I recommend a book called Year of Wonder by the lovely violinist and radio presenter Clemency Burton-Hill, it's a very personal selection of 365 pieces of classical music, usually 5 - 10 minutes long, which you can hear on YouTube every day. Some of it leaves me cold but I have also discovered some absolutely stunning music and my life has definitely been enriched by the book.
