Allergy - Where does it start & Where does it end?

I chaired an allergy workshop in G Hotel, Penang on 26 September 2010.

Assoc Prof Dr Amir Hamzah Abdul Latiff from Monash University Malaysia gave a very interesting lecture on "Allergy - Where Does It Start & Where Does It End?".

I found this is a very interesting topic, a question I have never give a deep thought.

Does allergy start before pregnancy, during pregnancy or after delivery?
Does allergy end as a result of prevention, treatment or sadly, death?
Is it true the answer is "from womb to tomb", as shown below?

I will spend more time on this topic -- Allergy.
