Britain is on 'autopilot' according to Marks and Spencer research

According to research by high street giant Marks & Spencer, humans make 250,000 'autopilot' decisions in their lifetime and many of these are making them unhappy.

According to the findings, we say 'yes' four times a day when we wish we hadn't and almost half of adults (47 per cent) admit this is because they don't want to let people down and over a third (37 per cent) believe it's simply easier to say 'yes' than 'no' to others.

Some of the top things we say yes to are working late, going to a social event we know we won't go to, visiting people we don't get on with and giving into kids for an easy life.

What's more, over two fifths of adults (44 per cent) have forgotten something whilst on autopilot including birthdays, paying an important bill, locking the front door and even picking the children up from school.

Marks & Spencer are launching Make It Matter Day on June 1 and want customers to share their experiences of when they have taken charge of decisions and felt happier because of it.

Commenting on the research, Steve Rowe, CEO, M&S said: ''Our in-depth customer study has shown that living life on autopilot is a direct consequence of us being so hectic and means that we don't always get the most out of life. However, for most people one small change a day can make a huge difference. That's why we are calling on the nation to stop saying yes to things that don't matter and start making more conscious decisions. Starting on Make it Matter Day on 1 June, we want our customers to share with us just how they are making decisions that count.''
