There is a group of older women I see at the pool. Many of them use walkers and canes. Some arrive with their swim floatie around their waist already. They are coming for a swim or aquafit. They chat in Portuguese, Mandarin, Italian and beautiful Jamaican English. Over a lifetime they have travelled tens of thousands of miles to meet on this Tuesday at this slightly shabby but well-loved community centre. I am sure their life stories could fill a library.
