my favorite exercise is pull-ups because they make you stronger and it's really easy if you do it on a daily basis, i can do 10 then i have to stop before i drop myself but I like to do more than just pull-ups on the pull up bar, on the pull-up bar i like to swing around like it's gymnastics or just hang upside down . i usually lift myself up with my legs wrapped around the bar, i know it sounds weird but im strong and i like doing dangerous things.
People littering and throwing rubbish on streets, to avoid it from happening place more bins in areas for people to throw their rubbish or address the situation to others.
