Does the time of year we are born affect the illnesses we are prone to? People who develop schizophrenia tend to have spring birthdays. Are there other such connections?

Yes. Loads of them. It's easy to research, so plenty of people have done. For instance: born between April and June? Join the club for anorexia, depression and suicide. You want your child to escape dyslexia? Avoid birth dates from May to July. You are more likely to be panicking about all this if you were born between September and December. In fact, the only months not connected to a later illness are January and August. The academic arguments on why these statistics exist are raging. Some blame lack of sun at certain times of the pregnancy. For anorexia it's suggested too-slim mothers are marginally fertile and more likely to conceive in the summer - thereby giving birth in the spring to daughters who may be susceptible, too. But put it in context: the differences between 'risk' months and the others are very small.

My husband, aged 40, has been feeling tired all the time for a year. His doctor called it TATT and has sent him for tests, as his ears are really hard. But how does TATT relate to the feel of his ears?

Your husband may be depositing calcium in his ear cartilage - a warning sign of a low cortisone level, perhaps because of a problem with his adrenal glands. This is one (rare) cause of TATT. More importantly, it could interfere with his ability to resist infections and give him low blood pressure. Happily, it is treatable.
