When you're fed up with self-obsessed twenty-somethings, try to remember that they'll be 33 one day. That's the age when they lose the 'all about me' attitude, research suggests.
By then, youthful selfishness subsides and people begin to consider others' feelings more often, researchers say.
When we reach 33, we are also more likely to make an effort with parents and grandparents and take a positive attitude towards ending feuds with family or friends.
The older we get, the more selfless we are in almost all areas of life - with the exception of volunteering in the community, the report says.
Most people agree that having children is the turning point in changing our attitudes towards other people.
This is when we apparently find ourselves worrying more about others and doing things for them, such as checking how they are getting home, offering to help with childcare and doing airport runs.
