           becuase the system to handle and implement now activities is already here, it is just a matter of coming up with new
           activities and not implementing them however, the activities databases are still hardcoded which means they cant be used
           for any year and do not update, further expansion on this project could benefit from API implementation to have dynamic 
           and more accurate databases for relevant activitiy info. */
