Dog owners tend to struggle less with cardiovascular diseases, which is not at all surprising since they take their dog for a walk on daily basis. This is not only a good bonding activity for them and their pet but ensures they move regularly, which is extremely beneficial for their health. If you do not own a dog, you can still go for a nice walk. 

Are you in a bad mood? Then go and make other people happy! No matter if you do so by spending money to charity, writing your grandparents a letter or carry the shopping bags for your elderly neighbor: You will quickly realize that doing something good for somebody else will make you happy as well.
