Not as much as I should really if I was honest. I do give some, but the actual amount is private. I also volunteer an hour or two a month working with local schools. Hope this anwers your question. Robin.
One of the most rewarding things I have done is take time out after finishing at university to go and work with a relief agency to build fresh water tanks for remote villages in Africa. I still support that charity and others too. I also take time out a couple of times a month to help run a community cafe in our town that provides free coffee, a chat and advice to more needy families in the area.
