My life has changed "a lot" due to my spinal surgery. I've had to give up so much I have loved. I had to close my martial art school and quit teaching fitness. I will never be able to do the things I use to. That's the bad news.
They both add so much to my life.
Finding those things that make you happy is important. Sometimes you have to reach really deep to find what makes you happy but it's time well spent. I'm 61 and doing GREAT! You can do it too. Go find your bliss!!!
