I live in a high rise block of flats on the 9th floor and soon they will be taking the only working lift out and placing a new one in. This we believe will take around 4 months. My question is I have high blood pressure and have been and will be in the next coming year tested for a hereditary heart problem. So currently unaware if I have this. Will walking these 9 flights several times a day be ok or should I asked to be temporarily moved till the work is carried out?
