Future Retirement Gift

There is a really old guy at my old job who I thought was like at least a hundred years old. But I found out that he is actually just 65 year old. The reason I found out his age was because it is his time to retire. I would have thought he could have retired a long time ago. They wanted to get him a retirement gift so I started looking online for retirement gifts engraved. There are a lot of choices online. I wonder though what is the right one to get for a guy who looks and acts so old. I guess something simple will work the best.
