LBTC- that's the first thing I thought of too! I developed allergies at 29 yrs of age and couldn't figure out what was wrong with me all of a sudden... just kept getting "sick"... finally it got outta control and I went to get checked... allergies! Bloodwork all fine so no indicator there either...

my doc said it's very common to develop allergies... appears to go nicely with my gray hair... sheesh...getting older blows!
