My dad survived cancer, what do i get him for Fathers day?

So my Dad gets colon cancer last year. Through surgery and quick thinking from his doctors its caught quickly and removed. No chemo or radiation needed. He's recovered physically from the surgeries, but mentally, maybe not so much. He was always a 'can do' kinda guy and since the mammoth surgeries last year, he needs to take things a bit slower. So on the road to recovery, last month he was complaining of a cold sore on his lip that wouldn't heal. He went to his dermatologist, turns out to be a mild form of Melanoma. Its removed and all is good. I guess I'm just so grateful to still have him in my life that I'm so totally underwhelmed as to what to get as a Fathers Day gift. So much has happened in the past 12 months that cashmere socks or Chanel cologne aren't going to cut it! So...any ideas for me???????????
