Because an old person can’t play for 90 minutes the football match will be divided in two parts. In the first ten minutes a team will play against the other team then in the second ten minutes other people will face each other so everyone will play only ten minutes. Because not running in football is boring in every 10 minutes there will be the golden three minutes: three minute in which you can run but tackle is forbidden in all the ten minutes. To make the sport more inclusive you can only do three touches with the ball and then you have to give it away. Every time you dont respect the rules is a free kick for the opposite team.

For people who have pulmonary proble like respiratory tract infections, tuberculosis, chronic obstructive pulmonary diseases and bronchial asthma it is almost impossible to play for a lot of time
