When you think about your best friends, you're probably thinking of people around the same age.

Maybe people you know from school, or at work, or who you grew up with.

But have you ever built a friendship with someone who's a lot older — maybe 30, 40 or 50 years your senior?

On the hack deep dive this week, we're hearing from people who reckon their intergenerational friendships give them access to insights, perspectives and wisdom they would otherwise never get to experience.

We hear from a 17-year-old with a group of friends in their 50s, a teenager who's learnt so much from chats with his elders, and we tag along with our own reporter Alice Angeloni on her hangout with her 82-year-old friend Clive.

Could friendships like these help with Australia's growing problem of loneliness?

We also catch up with a psychologist who reckons: yes.

Guests: 

• Danielle Kennedy, psychologist
