At New Ground in High Barnet, north London, 26 women over 50 have created the UK’s first cohousing community for older women — a purpose-built estate designed to help them live independently, avoid isolation and age on their own terms. Their story is told in their book, Our Later Years: Shared Wisdom on Ageing Powerfully Together. We went inside New Ground to see how this pioneering group of women live, share space and grow older together. Click the link to read more #women #london #housing #new

Life moves a little differently when you're first-time parents. Between sleepless nights and tiny milestones, it's easy to lose track of time—but somehow, we find it in the moments that matter most. A quiet smile, a shared glance, a few minutes together while our baby sleeps. With Timex on our wrist, every second reminds us that even in life's busiest season, there's always time for each other. @Timex Philippines #TimexPH #SS26 #AnalogLife #MakeTimeYours
