Eep... Missed the no writing, but also forgot to add that there's many voice to text softwares out there, but most smart phones and computers have it already installed. Novels might be a far reach, but a bit of lyrical word play or poetry shouldn't be too far reaching.

Solitaire is another one, especially with real cards (computer versions you seem win too much gets boring). Board games can also be fun, play your favorite color/piece against your least favorite, especially when you play the old games like chutes and ladders, or candy land... Not so much fun if playing battleship though . And testing yourself with trivial pursuit cards can be fun too. Heinz ketchup put out a version for smart phones that free.

And if you have any technical people around you, there's another thing like downloading emulated versions of old school games (donkey kong, dr. Mario, Tetris, Pong) to play on the computer.
