Chris is joined by Giles Yeo, Roger Buckley, Andrew Pontzen and Kerstin Goepfrich, and they enjoy a mince pie or two while answering listener questions, including: why isn't love blinding; are glasses or contacts better for your eyes and what would happen if you brought a thimble of neutron star to earth? Plus, the team discuss the supposed benefits of the Mediterranean diet and debate the worst science movie mistakes.
