The 40 signs of a mid-life crisis have been a revealed in a new poll.
The most popular answer is the desire for a simpler life.
In second place is still going to outdoor music festivals like Glastonbury.
Another key signal is when you starting looking up old boyfriends and girlfriends on social network sites like Facebook.
Fears over the future feature in a lot of the top 40 entries - particularly job insecurities.
It's why so many 40 and 50somethings are going on sites like Twitter - in the hope that their employers will think they are digitally savvy.
Another theme from the survey is worries over appearance.
The findings come in a poll of 1,000 people by Crown Clinic in Manchester, Britain's leading hair transplant centre.
It found the most popular age for men to reach their mid-life crisis was 43.
This is the same age as the Labour leader Ed Miliband. David Cameron was 43 when he became Prime Minister.
The phase typically lasts between three and ten years in men - twice as long as women.
Women hit their mid-life crisis at 44 - the same age as Hollywood beauty Jennifer Aniston.
It typically lasts for between two and five years in women and is linked to the onset of the menopause.
The term mid-life crisis was first coined in 1965.
It described the time when adults come to realise their own mortality and how they have less time left in their life than they have lived.
Early analysis suggested a mid-life crisis could happen anywhere between the ages of 40 and 60.
But its onset has been going down in age over the years.
This is linked to heightened career prospects for younger people and the increased pressure on all of us to succeed.
The average age of company chief executives has gone down from 59 to 48 in the last generation.
Body insecurities are a big part of the mid-life crisis for men and women.
The average age when men seek a hair transplant is 45.
Surgeon Asim Shahmalak from the Crown Clinic said: "As people get older they worry increasingly about their appearance and want to recapture their youth.
"At Crown Clinic, we have found that people are far less shy about making quite radical changes to their appearance as they get older.
"Men are less embarrassed to seek a transplant to combat baldness.
"They worry about losing their jobs and know that a more youthful appearance will make their more attractive not just to the opposite sex but employers as well.
"It is interesting that David Cameron was 43 when he became Prime Minister - the typical age men's mid-life crisis starts.
"His hair has thinned noticeably since he came to power and stress is likely to have been a contributing factor.
"It is my so many male executives in their 40s come to clinics like ours for help."
Crown Clinic has seen a 25% rise in bookings in the last five years as more men and women seek transplants for thinning hair.
It is a big favourite with celebrities like Embarrassing Body star Christian Jessen, 36, who has had two hair transplants there because he has felt under pressure to look good on TV.
Other stars such as actor James Nesbitt, 48, have told how having hair transplants have breathed new life into their careers.
