This week, we’re talking relationships. When we’re pushing towards a goal, or just generally having a tough time, many of us will instinctively turn to our friends, family, colleagues, or even pets for support. But… why? What is it about our relationships that can help pick us up when we’re feeling down? And why is nurturing those connections key to both our physical and mental health, and achieving our goals? This week, we sit down with Dr Anna Machin. She’s an evolutionary anthropologist who’s spent her career studying the science of close human relationships. From the neurochemicals underlying your tightest friendships to the best social activities for your brain when facing down deadlines, we’re digging deep into how our connection with others helps us get where we want to be.   This is On Your Marks.
