The resident Grandpa here does the garden - he's not passionate about it, but he'll cut the grass and sweep the paths and generally do whatever's needed. He always puts the bins out/brings them in, takes our DS's dog for a long walk every day - and sometimes takes our DD's dog as well so they have a run together. He isn't averse to cooking, and will often take the list and do the shopping if I'm busy doing something else. Most mornings he washes up anything left from the previous evening, and gives the hob and worktops a good clean.
He can sit and endlessly do sudokus on his laptop, and he reads a lot too - when he was working he only ever read on holiday, now it's all the time.
I don't know why I sometimes moan about him to be truthful, he's rather a good egg really
