Patient discussion about impact

Q. what is the impact of masturbation? because I diden't find my girl?

A. the only physical impact i know is an addiction that can occur when doing it way too much. doing it releases chemicals in our brain in the pleasure areas. you can easily get addicted to it.

Q. This is mostly for people who have ADHD/ ADD or know someone with it. How is it impacted your life? If you have ADHD/ADD, what type of an impact has it had on the people who are close to you? If you know someone with ADHD/ADD, how have they made an impact on your life?

A. ADD can be a little hard to live with especially if it's not being treated. Having ADD makes it hard to stay focused on one thing for a long period of time. I have to make sure that I pack plenty to do when i go to school or else i would never make it through the whole day in a good mood. It isn't all bad though, I'm really good a multi-tasking. I can be working on six different things at once and get them done in a timely manner, whereas if i was just working on one thing it would most likely take me the whole day to finish it. Hope this helps.
