I am a firm believer that when you change your surroundings... it can be a wonderful thing for your mind, body and spirit. Sometimes a persons surroundings is not conditioned to the way that they should be living and it can hurt them or impact them greatly physically and sometimes emotionally. As you age, situations in your life change and sometimes stairs may be hard to climb or walking distances may not be an easy thing to do anymore.. your living environment is huge when you are a senior and making sure that you have your surroundings meet the LifeStyle you are now looking for is important. This is why holding onto an old house that you use to live in before is not always a good thing unless you thought out your future conditions and that house meets those needs as well.
Even when you are young, sometimes selecting to live in a neighborhood that may not be the safest may impact your life greatly. So when you're looking to make a major change in your life such as moving to a new home or changing around your living environment... consider all elements of design and make it peaceful and joyful space that is full of the LifeStyle that you want and need. It is important to stay healthy and your living environment contributes to 80% of your health and that is a huge number. I am sure that safety is the number one factor in these percentages but I would agree that it is one of the most important.
