You may just want to helpfully remind him of his own impending mortality. Or, perhaps you want to give him the gift of collected wisdom to guide him on his newly begun journey as a family man, or a businessman, or some other type of man.

Finding the right gift for someone going through such a transition can be tricky, and given that there are a ton of great 30th birthday gifts out there, it can be difficult to decide which is the right one. Some guys might see it as a last hurrah before finally making the full transition to adulthood.

Turning 30 can mean a lot of different things for men.
