Many of us live on fixed incomes and cannot spare a lot of money to help others, however, there are many ways to exercise compassion. Some suggestions, when the pandemic eases, are:
Give unwanted clothes and other items to charity shops.
Help in a charity shop.
Get in contact with a charity for the blind to read stories onto tapes, if this is an interest of yours.
Hold a charity event, or enter one (eg a walk or race perhaps)
Look at your finances each year and see if you can spare more money for any charity (or if necessary, less)
Leave something in your will to a charity.
Look at helping a smaller charity, perhaps a local one.
