Holding hands into old age, laughing at your partner's jokes even when you don't find them funny and knowing when to bite your tongue - that's true love, according to those who've experienced it the longest.
A study of 2,000 over 50's explored the real extent of the 'for better for worse' elements of long-lasting love to unveil 50 signs of the real thing- with building a home together and not being afraid to show vulnerability high on the list.
While kissing at least seven times a week was critical to keeping the fire burning year after year.
Researchers delved into the intricacies of a successful relationship and unearthed the 50 most popular responses to the question 'what is love?'.
Saying 'I love you' at least nine times a week was also integral to long-term happiness, results showed.
Encouraging silliness in one another, learning to get along with the in-laws and avoiding jealousy if the other person spends time with the opposite sex were also deemed key factors in cementing a long-lasting love.
The research, commissioned by www.retirementmove.co.uk, found that on average love blossoms four and a half months into a new relationship.
Only nine per cent believe in love at first sight, but just under half of those polled went as far as to say they believed in the concept of 'the one' when it comes to romance.
Richard Drew, CEO of www.retirementmove.co.uk, said: "The list of what it takes to make love last covers a range of warm, quirky and honest pearls of wisdom from people who have really experienced love in all its forms.
"What the data reveals is that the warmest bonds and most valued memories aren't necessarily always the big standout things like exciting holidays or calendar moments, but actually in the living and enjoying of one another day to day.
"Building a home together proved a central concept to long-lasting love and shows that so much of the way we think about love comes from that sense of feeling at home and belonging to a place."
Results showed that home really is where the heart is - when quizzed on their favourite memories with their partner, Brits were most likely to cite 'just being at home with them', with two thirds saying these beat holidays, birthdays and Christmases.
Nine in ten think making a home together is what real love is all about and one in six people proposed to their partner in the living room.
But love doesn't always come easily and over half (56 per cent) feel they don't fall in love easily.
49 per cent of Brits said they would choose falling in love over winning the lottery, results showed - although more than a quarter (29 per cent) would rather take the cash.
Nearly a quarter of those retired said the best thing about not having to work was getting spend quality time with the person they loved.
While two thirds thought love definitely gets stronger with age, just one in 12 per cent thought otherwise.
Richard Drew added: "This is a great 'window ' on retirement living and loving - and three of the top ten secrets to lasting love revolve around the home, not being apart, even if you're just sitting in silence with your loved one.
"Our personal service ensures that we get to know our customers hopes and dreams for their new home and they can enjoy the next stage in their lives."
