Loneliness doesn't always stem from being alone. For architect Grace Kim, loneliness is a function of how socially connected we feel to the people around us -- and it's often the result of the homes we live in. She shares an age-old antidote to isolation: cohousing, a way of living where people choose to share space with their neighbors, get to know them, and look after them. Rethink your home and how you live in it with this eye-opening talk.

How cohousing can make us happier (and live longer)

Loneliness is less about being alone and more about lacking meaningful social connection, often hidden behind suburban ideals or endless digital contact. In cohousing communities, people intentionally share spaces, dine together, and look after one another, building bonds that single-family homes often erode. Studies show that isolation significantly increases the risk of early death, making social connection a true health issue. Cohousing revives the age-old value of communal living, offering not just happier lives but longer ones.
