What is the best gift I can get for my husband on his birthday?

We've been married a year and this is our first birthday as a couple. If possible I'd like a mans perspective on this, on what to do or get for him, as its quite hard to find the right gift for a man. He's been through a lot, cancer, chemo all at a young age, his mother being ill and his father having 2 heart attacks. So lifes been tough! It can be anything, doesn't have to be materialistic, but something that would make him the happiest.
