You won't find tanned selfies, thirst trap photos or filtered street shots on Eileen Smith's Instagram, but the 80-year-old Dublin grandmother's combination of effortless glamour and pared back captions have won the hearts of over 50,000 followers. 

On last night's How to Live Better for Longer, Smith - better known by her Instagram handle @eileenstylequeen - made her television debut, sharing her secrets to maintaining a stylish life. She spoke to host Dr. Eva Orsmond about staying active and how she motivates herself to put her best foot forward each day. 

Her top tips? Staying fit, meeting friends and getting up, getting dressed and getting out. 

As any devout follower of the Style Queen would know, Eileen loves a day on the golf course, often sharing snaps of her vibrant jumper-and-trouser combinations or posing for a photo along the scenic Wicklow coast. 

Going out to meet friends is also a central part of her routine, with many glitzy outfits pulled together for a coffee date at the local cafe or a wander around Avoca in Wicklow. 

"It is very important to have friends. In my world it is top of the list," she said.

This was echoed on the show by Professor Ian Robertson, a neuropsychologist, who spoke to Dr Orsmond of the importance of social interaction.

"Chronic stress is not good for ageing. In fact, it accelerates it because the body generates cortisol which is toxic to the brain and body in high levels if it's prolonged," he said.

"Therefore learning to manage stress is very important."

Explaining that she only began using the social media site to stay in touch with family in other parts of the world, Eileen explains that it's a natural fit for her love for fashion and fondness for keeping up with loved ones. 

"I have three daughters who are very into fashion but they live away from Dublin so we used to send photographs to each other whenever we bought something," she said.

"We would send a photograph and say, 'What do you think of this?'"

Eventually, one of her daughters suggested she try the social media channel, and 50,000 followers later Eileen is a bona fide influencer. The majority of her following is aged between 17 and 26, proving that good style never dates. 

"It does stun me because wherever I go now I could have at least 13 people come over to me and say, 'I follow you'. I just enjoy doing it. I like style."

When it comes to motivating herself each morning, Eileen shared a simple trick that keeps her looking and feeling her best. 

"I have a little bit of paper beside my bed which is framed and it says 'get up, dress up and get out'.

"And I look at that on a winter's day when you would not feel like getting up and getting out and that makes me do it."
