Absentgrana - be careful when you give up smoking - my husband did at 62 after 50 years, and the shock to his system ruined his health. He now uses step one nicotine patches permanently and is getting better.
When you give up, go on the nictine patches for much longer than they say. It is not PC to say there is a downside to giving up, but there is, and much grief would have been prevented if we had known. Nicotine helps the immune system and is good for brain power. This does not mean it is OK to carry on smoking, but it does mean you should not give up the nicotine suddenly.
I never had that particular horrible habit - smoking - but I've plenty of others. Getting mucky in the garden and just not caring is one!
