But, having been around the block a few times, they're also pretty good at giving out advice.
Now a new book called Grandmother's Wisdom, sees gran-of-five Lee Faber share her pearls of wisdom on everything from cooking, cleaning and gardening to bringing up kids and curing ailments. Apparently it involves lots of vinegar and lemon…
Five of our favourite 'gran tips' from the book include:
1. If you bite your tongue, place a used, wet teabag on it to ease the pain.
2. To cure hiccups, drink a glass of warm water with one teaspoon of cider vinegar mixed in.
4. To stop mosquito bites, eat food rich in vitamin B1, such as wholegrain cereal, porridge, brown rice, diary products, red meat and nuts. It puts them off biting you.
5. To make sure you get rid of every shard of glass after a breakage on a hard floor, dampen a sturdy sheet of kitchen roll and wipe it over the area. Do this several times, using new paper, and you'll pick up all the flecks of glass.
Grandmother's Wisdom by Lee Faber is published by Michael O'Mara, £9.99.
