Once you get old, slowly but sure people will leave you behind and you will end up alone, lonely in your so called "House". While people who struggle in marriage's life will live in a place that called a "Home". Let see how much time you will able to have fun? one decade? or two decades? When you are 40+, you won't be able to have fun like you used to be, your stamina will dry up and you won't be fit anymore (especially have sex with women).
