I'm applying for a new job in a different department with my current
employer and the application form requires me to fill in a section regarding
disability.  It asks if I am disabled and defines disability as "a physical
or mental impairment that has a substantial and long-term adverse effect on
his or her ability to carry out normal day-to-day activities"

I have brittle asthma which my employer has known since I was first employed
by them and they have a letter on file from my doctor.  I had 15 days
absence in the last 12 months due to asthma - no more than 1 or 2 days at a
time.

I've never regarded myself as disabled but believe more severe asthma meets
the definition of disability in terms of the Disability Discrimination Act
1995.

I live in the UK.

Does anyone have any experience of this?  Or have any suggestions?
