All I do at the moment is a bit of litter picking when the group meets, and I'm on the committee of our local history group, if that counts. At home I knit for our premature baby units and assemble jigsaws for a local jigsaw festival, which raises money for local charities.
Helping with the grandsons takes priority for us at the moment though and we also like to make time for ourselves now that we're retired. I was planning to volunteer literacy support in primary schools when we're not needed so much, but we have another grandson on the way, so I'm not sure when that will be!
