This is one of the most honest conversations in the whole series. In episode five, Sarah Woodcock talks about mental health — not in a clinical way, but in the real, day-to-day experience of living and working in a shift-based world where your body is always tired and your life doesn't look like everyone else's.

Sarah opens up about "high-functioning fatigue" — looking fine, working fine, performing fine, while feeling completely depleted inside — and how the constant switching of times, environments and pressures means your nervous system rarely gets to settle. She's honest about the emotional cost: feeling more reactive when you're tired, snapping at family after a long day of demanding passengers, and the guilt that follows. She talks about the relationship toll too — missing weddings, birthdays and Christmas mornings, feeling out of sync with friends, and living in a completely different rhythm to everyone around you.

And she shares what helps: recognising burnout early instead of pushing through, giving yourself permission to slow down, and — importantly — talking about it. Explaining to her family when she's had a hard day, and realising through other crew that she's far from the only one feeling this way.

If you've ever felt emotionally flat or like you're running on autopilot, it doesn't mean something's wrong with you. Sometimes the most powerful thing is to acknowledge it rather than push through in silence.

Next episode: the finale — can you actually thrive in shift work, or is it just survival?
