Recently, I caught up with my friend Thys. It would have been easy for the conversation not to happen. We have both had our share of health issues, life gets busy, and before you know it, far too much time has passed.

But we did connect, and it was such a pleasure to talk again. It reminded me that friendships rarely look after themselves. They need our attention—even when neither person has deliberately allowed the distance to grow.

Loneliness and isolation are real problems in later life, and losing touch can easily become the default. Staying connected requires some effort from all of us, but the reward can be as simple and valuable as a good conversation with an old friend.

In Why Brains Need Friends, neuroscientist Ben Rein explains what happens in the brain when we connect with others—and why those relationships matter to our wellbeing.

The book adds scientific weight to something many of us already sense: friendships need attention. It also offers practical ways to build a more connected life and look after the relationships we already value.

This short TED-Ed video explores what helps friendships endure, from regular contact and shared time to honest conversation. It’s a thoughtful reminder that even the strongest friendships benefit from attention and intention.

Catching up with Thys reminded me how easily good friendships can be crowded out by health concerns, busy lives and the simple passing of time. The book and video reinforce the same point: connection matters, but it needs a little care from all of us.

I hope your weekend brings a good conversation with someone whose company you value.
