First of all, we should keep good habits of work and rest. Middle-aged greasy uncle, as the name implies, is that people begin to produce all kinds of oils after middle age. In fact, traveling affects your mood and makes others look disgusting. But have you ever found that when you were young, you were still a big skin, but after middle age, you became a big skin? Oily skin has a lot to do with your endless staying up late.
The second is to keep exercising. Many men will definitely be fat after middle age, but being fat will make people feel that your image is particularly bad. So in order to show your charm, you should lose fat and gain muscle. This requires you to keep exercising and strengthen your physique. Of course, you can't see the effect in a day or two, so you must stick to it.
Finally, keep a pure heart. Although I have entered middle age and seen all kinds of storms, I still have to love life and be curious about everything. Therefore, you should make yourself look young, which will also help you keep a happy mood. In short, if you don't want to be a middle-aged greasy uncle, you must change yourself from the inside out.
