>>I've suddenly become lactose intolerant and allergic to milk at the ripe old
age of 35.  Does anyone know of medical answers of why this would happen?<<

At age 26 I became allergic to all dairy, egg, garlic, coffee, salmon, asparagus...and some
other stuff. My allergist says it is common for kids to have allergies but that they usually dip
down in the teen years and re-emerge as a person approaches their 30s.
