Play helps develop and improve social skills:
Social skills are learned as part of the give and take of play. During childhood play, kids learn about verbal communication, body language, boundaries, cooperation, and teamwork. As adults, you continue to refine these skills through play and playful communication. For example, your brain comes more healthy and intelligence, your body resistant increase. Oscar (a friend work) said me that when he came a dad he usually used to get disgusted because they never could play with his friend, but when his son grow up they began to play with his son and now he’s more happy than before.
Play can heal emotional wounds:
As adults, when you play together, you are engaging in exactly the same patterns of behavior that positively shape the brains of children. These same playful behaviors that predict emotional health in children can also lead to positive changes in adults. If an emotionally insecure individual plays with a secure partner, for example, it can help replace negative beliefs and behaviors with positive assumptions and actions
In the other hand, could you let your children take the lead? Well you'll become part of their game rather than trying to dictate the play. In pretend play, let your child call the shots, make the rules, and determine the pace of play. Ask questions and follow along—you’ll likely get drawn into imaginative new worlds that are fun for you, too.
However, to sum up I think people between 30-60 have to try this options to dessestres in daily life, so don’t worry about your age and just play like children do and be happy, the life is one and you decide how to living.
