2 . Last weekend, I said goodbye to another dear old friend. We had 12 fine years together, but our relationship was becoming dysfunctional(不正常的). Unwanted emissions and serious health problems were the final straw, leaving me with no choice but to make a trip to the knacker’s(收废汽车者的)yard.

I am now car-free for the first time in 20 years, and it feels strange. When I gave up meat, I did so mainly for environmental reasons, and I didn’t miss it at all. I would like to say the same about my car, but I can’t. It was first and foremost a financial decision: keeping the old car on the road was getting too expensive.

But doing the right thing for the wrong reasons is still doing the right thing — I now have a chance to rethink how I move myself and my family around, and can try to find a more environmentally friendly means of transport.

Going car-free is, I think, a lifestyle change that many of us are going to make over the next few years, as car ownership becomes increasingly unnecessary, expensive and socially unacceptable. However, it is easier said than done. Now my car is gone. I still need to get around. But how? I already cycle to work and use public transport when appropriate. But there are some occasions when a car seems to be the only way.

I won’t buy one: I have joined a car-share program and will use taxis more often. I will hire a car if I need to drive a long distance. But then I am still travelling in fossil-fuelled cars(燃油汽车), like when I quit meat and ended up eating more cheese. I fear I may have swapped one environmental problem for another.

I am also afraid to think about the ultimate fate of my car. I have just offloaded more than a ton of metal, plastic, rubber, fabric, electronics, oil and petrol that will end up in a landfill. There are millions of similar vehicles in the UK alone that will have to go somewhere.

Maybe I am overthinking it. According to Charlie Wilson, a climate scientist at the UK’s Tyndall Centre for Climate Change Research, getting rid of a private car is no doubt a positive step to reduce CO₂ emissions.

He points to research by the OECD’s International Transport Forum. “They showed that moving from a private vehicle fleet(车队)to a shared vehicle fleet can greatly cut the number of vehicles you need to deliver the mobility that we need and want. If that vehicle fleet is electrified, you can also bring CO₂ emissions close to zero.”

So in other words, just get rid of your car.

3 . Studies on the importance of sleep for health and the various effects of not having enough sleep have long been well-known. Being short of sleep can lead to poor memory and daytime sleepiness. It’s also been connected to diseases and weakens immune(免疫的)function. However, more than three-quarters of us fall asleep after 11pm and nearly a third stay up until 1am.

The concept(概念)of sleep procrastination was introduced in a 2014 study by Utrecht University in The Netherlands, which explained that it meant “failing to go to bed at the intended time, while nothing prevents a person from doing so”. If so, it will bring terrible results.

Studies have shown that “bedtime procrastination” is connected with a person’s working life during the day. “They feel out of control in their day life and the night is when they can be free,” says Dr Saliha Afridi. “It is full of things they ‘have to do’ rather than what they ‘want to do’. ” Studies have also found that increased working hours and the reduced leisure time may cause much stress and sleep procrastination. On occasion, people have trouble with feelings, concern and loneliness, so they were controlled by using social media, making them stay up late.

So how to avoid it? People should avoid thinking too much before bedtime and stay away from digital devices. Besides, taking a warm shower before bed and going to bed at the intended time are also important.
