1, with a heavy beard.
Generally, men with heavier beards are healthier, which is the same as the case of heavier armpit hair mentioned above. Men who breathe heavily are generally due to the exuberant secretion of male hormones in their bodies, and according to research, men with heavier beards will perform better in their husband and wife lives, which is also because men secrete more hormones, so if we see a man with a heavier beard, it also means that this man is healthier.
2. Large lung capacity
If a man's lung capacity is particularly large, it probably means that he often takes physical exercise in his daily life, and the chances of smoking are very small if he takes high-intensity physical exercise for a long time. Because the lung capacity of people who smoke frequently is not too large, it also means that this man's physical fitness is quite good and there is no bad hobby.
3. Big nose
In fact, whether a man is healthy or not can also be seen from a nose. For example, if a man has a big nose, it generally means that he is very healthy and particularly smart, because scientific research shows that a boy with a big nose is more conducive to absorbing nutrients in the air and providing sufficient support for his brain, while a man with a small nose and a narrow nose is often accompanied by a state of insufficient oxygen supply to his brain, which also explains why a man with a big nose is smarter.
