There has never been a more important time to keep your immune system fit and healthy. And as Graham Lawton discovers, there are now ways to keep it younger than you are.

WASH your hands religiously for 20 seconds, sneeze into your elbow, avoid touching your face, stay 1 meter away from all other people and, as a last resort, self-quarantine for a week with only your emergency rations for company.

But ultimately, one of the most important things standing between you and a deadly bout of COVID-19 is your immune system.
