People aged 68 or nine year olds are likely to be the most happiest as their priority in life is to 'have fun'.
According to a new UK survey, nearly 64% of those aged 68 listed having fun as one of the most important concerns in their life, while most nine year olds were happy as a result of not having financial, relationship and career concerns, The Telegraph reported.
The survey of 2,000 people aged five to 80, by sweet company Juicy Drop Prop investigated the exact points in life where people are least worried and more concerned with having fun.
Those in their 60s are the most adventurous and thrill seeking age group, with 34% listing skydiving, bungee jumping and surfing as 'must do' activities.
One in five over 60s showed their adventurous streak by describing an action-packed adventure holiday as their ideal break.
However, younger participants proved less daring, with only 5% of those in their 20s-40s choosing a similar holiday.
The study suggests that younger adults do not attribute the same importance to enjoyment as children and over 60s.
The majority of people aged between 20 and 40 had more pressing concerns, with 72% prioritising paying off debts and furthering careers above having fun.
The fun loving attitude of over 60s is reflected by nearly half (47%) of children considering their grandparents to be the most relaxed and fun members of the family, more so than their parents.
A majority of children under 10s (78%) surveyed said that getting a job and missing out on fun were the worst things about growing up.
