One-in-three people will suffer some kind of allergy at some stage in their lives. For most it means a runny nose, a rash, or sensitivity to certain foods. But not for 30-year-old Johanna Watkins .

Off limits for Johanna are most foods, smells, sunlight, friends, her parents ... and even her husband.
