Smoking
Say if a person smokes and he/she thinks it here own business, no one else has a right to interfer. Those people eventually want to settle down and they look at people who don't smoke and they don't give a hoot what that person thinks, this is most people. Thinking its none of their business.
When eventually that persons lungs collapse and they are coughing at night times keeping their partner awake, their health deteriating and they need help/care from the partner. Do they then think is it still none of their business! Lots of non smokers are suffering a lesser life and more responsibility sooner than they should be because of selfish views of individuals who do not think or care of who may end up being dumped with their body and life because they wanted to smoke.
What are your views on this! And smokers please be honest. Unless you intend never to live with anyone the good luck to you its only the nhs system which will be drained then :)
