I would say bicycling because jogging and jumping jacks can be bad on your knees because of the impact. Biking is pretty smooth though and wouldn't have much of an impact. Hope this helps :)
The purpose of the organs of the male reproductive system is to perform the following functions:
-To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
-To discharge sperm within the female reproductive tract during sex
-To produce and secrete male sex hormones responsible for maintaining the male reproductive system.
Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles.
You can check up on others and ask what they’re doing. Keep an eye out for suspicious activity and if you feel like someone is in danger, intervene by making responsible choices, depending on how severe the situation is. The benefit of looking out for others safety is also making sure of your own so always be aware of your surroundings.
