Hi, have a few questions: 1) My house's main door faces the living room's window directly, does this cause any leakage in something?? Does it help if we cover the window that is facing the door directly with a blind? 2) Also, my husband has beenfalling illmore frequent than ever since we moved in5 yrs ago. Is there anything that we should keep a look outfor? 3) I live in a HDB maisonett. My common toilet's door (upper floor)faces the staircase directly. When the toilet door is open,my basin,tap and mirror is also facing directly at the staircase. Will this affect us in anyway? Kindly advise.
