你今天感觉怎么样？
如果你因为睡不好觉而晕头转向，或者你宿醉了，或者你有太多事情要做，你就会很可能心情不好。如果一切看起来都像是在努力，而且你还很消极，那你最不希望别人告诉你“积极一点！”。但是拥有这种心态会比你想象的更有好处。当然，培养积极的态度说起来容易做起来难。不是每个人自然而然都是这样的。
当你情绪低落的时候，很难去乐观地看待问题。但是美国的一项研究发现乐观主义者，比起那些生活态度消极的人来说活的更久。它揭示了生活态度积极的人的可能性，就是他们能活到 85 岁甚至更久。所以也许想到长寿。可能会鼓励你用更富有希望的人生观去看待生活。
这项研究得出结论，乐观主义者可能会觉得更容易去控制情绪并且减轻压力。当压力影响免疫系统时，乐观主义的人有可能能够更好的面对感染。波士顿大学医学院的教授露易斯娜李，这项研究的研究人员，告诉英国广播公司：“我们的发现表明了提高乐观水平，可能可以促进长寿和健康老龄化”。她建议悲观主义者可以从这些事情中受益，像是想象一个一切都会好起来的未来。但是如果你是一个喜欢看事物坏的一面的人，那么透过只看到事情好的一面对你有用吗？
接受这个观念就是我们每个人都有问题，并且我们每个人都不一样。有些人说，我们最好去纪念正面的事物，这可以帮助我们掌控自己的情绪并且不要沉湎于我们生活中消极的一面。人们一直在给英国广播公司提供他们的个人建议。
关于保持健康积极的生活方式，薇琪西斯卡说：“音乐滋养我的灵魂，幽默感让我对事物保持洞察力，并且我有爱我和关心我的好朋友”。皮帕肯尼迪说“对你所拥有的心存感激并且大量的巧克力可以提供帮助！”。俗话说‘健康的身体引导健康的头脑’。这可能就是为什么其他人推荐做瑜伽和冥想，以及保持健康有助于保持积极的人生观。

How are you feeling today?
If your head's in a spin because you've had a bad night's sleep,or you're hungover, or maybe you've just got too much to do,the chances are you're not in the best of moods.
If everything seems like an effort and you have a negative attitude,the last thing you want to be told it to 'be positive!'
But having this mindset could have more benefits than you think.Of course, developing a positive attitude is easier said than done -
it doesn't come naturally to everyone.When you're feeling down in the dumps,it is hard to be optimistic.
But a study in the US has found that people who are optimists are more likely to live longer than those who have a more negative approach to life.
It revealed the likelihood of positive people living to the age of 85 or more to be higher.So, maybe the thought of a longer life might encourage you to have a more hopeful outlook on life.
The study concluded that optimists may find it easierto control emotions and get less stressed.
And as stress impacts on the immune system,it's possible that optimists cope better with infections.
Professor Lewina Lee from Boston University School of Medicine,who worked on the study, told the BBC that:
"Our findings speak to the possibility that raising levels of optimism may promote longevity and healthy ageing."
And she advises that pessimists could benefit from doing things like imagining a future where everything turns out well.
But if you're a 'glass half empty' type of person,could seeing the world through rosetinted glasses work for you?
Accepting that we all have problems and that we're not all the same helps us to get a grip on our emotions.
Some people say it's best to celebrate the positives and not dwell on the negative parts of our lives.
People have being giving the BBC their personal advice on keeping a healthy and positive approach to life:
Vicki Siska says "Music feeds my soul,a sense of humour keeps things in perspective,and I have good friends who love and care for me."
And Pippa Kennedy says "being grateful for what you have - and lots of chocolate - helps!"
The saying goes that 'a healthy body leads a healthy mind'
which is probably why other people have recommended doing yoga and meditation as well as staying fit and healthy to help maintain a positive outlook on life.
