Love and lust : eyewitness accounts, emetophobia.

The first item on the programme is about love and lust. Raj Persaud speaks to Dr. Helen Fisher about her research which aims to prove that love is produced by serotonin levels and as such effects us like any other kind of mental addiction. The second item is about how reliable eye witness accounts are. Persaud takes part in a memory recall experiment. The final item is on 'vomit phobia' or emetophobia and we hear from Leanne Ingram who suffers from this disorder.
