Radhika Merchant has married her partner Anant Ambani, the youngest son of Asia’s richest man, Mukesh Ambani. When your Dad is the 11th richest person in the world, worth over $112bn, you can afford a wedding year, rather than a wedding day, right? After seven months of celebration, Marnie and the panel review the festivities to see if there is any science lingering under the ‘I dos’. Hear of Hindu wedding customs and superstitions, and why something called evolutionary lag might be behind traditions that make very little sense.

Also, rings, but not the wedding bands. Professor Valerie Trouet, from the Laboratory of Tree Ring Research at the University of Arizona tells tales of the ancient circles found within trees harbouring secrets of climates past and future.

Plus sleep divorce, why it might be a marriage saver, and finally putting to bed who has the best sleep pattern, the night owls or the early birds.
