I just came back from visiting with a friend who is stopping chemotherapy and starting palliative care. One of the sweetest and most faithful people I have known, has had a miracle in surviving this cancer 9 years ago, but is at the end of the battle now. At least her young kids have had a lot of time with her, but it still is a major kick in the gut.
Cherish what you have, we have a limited time only in our lives. Try to make a positive difference as she did.
And enjoy your passions . . . such as cars.
