POV: You’ve headed on a long-haul flight to a tropical destination. You’ve broken away from the cold, dark British weather and are finally feeling the warmth of the sun on your (SPF protected) skin. You’re glowing from your head to your... er, knees.
That’s right. Your legs have stayed the same pasty vitamin D-deprived hue as when you began your trip, unchanged no matter the shift you’ve just put in on your sun lounger.
