Any sort of crafting hobby, which ranges from making clothes to making swords to making furniture.

Graphical arts, digital and analog (which covers everything from painting with all different types of paints to mixed media, large format, small format, from the side of a building to the size of a grain of rice)

These are all mostly looks-based, but you can also make things that do things, make electronics, restore old electronics, go antiquing for vinyl players, go antiquing for anything else.

Join a choir, join a band, join a barbershop quartet, go to the Portsmouth Maritime Folk Festival and listen to sea shanties.

The list goes on.
