I live in the UK, so I get 25 days off work, and I take full advantage of that, I rarely do staycations.

I'm about to buy a property and I'm deliberately going to get a mortgage where my monthly payments are not as much as I can possibly afford, but a bit less. This means that it will take me longer to pay it off, and overall it will cost me more, but I will have more disposable income today to spend on life's pleasures.

I don't have kids and don't plan to.

I stay physically active, just simple going to the gym 5-6 days a week. And I think this is really important. It will keep your body in shape and by the time your 60 or 70, you'll be able to do much more than your average peers who spent their middle age doing office jobs followed by evenings in front of the TV. And here, instead of my 41-year-old self, I'm going to use the example of my mum. She's turning 70 next year, but it was only when she was 68 that she started taking swimming lessons and she got to love it. It was also around that time that I floated the idea to her "why don't I take you for holidays to New York". She was all "no, no, I'm too old, it's too much walking, you took me for a holiday to London when I was 55 and I was totally exhausted, I wouldn't be able to do New York at this age." Now that she's had over 1.5 years of almost daily swimming (and cycling, she's also a keen cyclist) - she said yes. She said she's feeling perfectly fine doing long walks, she's more energised, and she already gave me a list of what she wants to see in New York.

Other than physical activity, scientists seem to agree that the other two pillars of long and healthy life are good sleep, and good diet. For the former, I recommend reading Why we sleep by Matthew Walker. And good diet means varied diet, vegetable-rich diet, and low-calorie diet (too many books agree on that for me to recommend a specific one).
