As beautiful as it sounds, but in practical, it's not that beautiful. Imagine your spouse is sick, sick enough to make him/her helpless. He/she cannot stand without someone's help. But, in the other end, the sickness is hurting, so painful that makes you become someone else, someone's not as nice as you once were. People cannot stand you, as you cannot communicate in any ways possible. You need people to take care of you, but no one can stand you, isn't it ironic, don't you think?. The only person that can (and forced to) take care of you is your spouse. But, your spouse is human too. She/he can get sick, mentally and physically, and has her/his own life that needs privacy and freedom. Can you really sacrifice your life for other person and really committed to it? Are we really meant it when we say in our wedding: ...in sickness and health, till death do us part...?
