D. Bc it’s not too long of a time to stretch out of your day and it’s almost everyday so your body adjusts to your body muscles being pulled. It’s good to stretch
True..but it differs on the body weight
I couldn't find that much but I found the same question as yours and this is another person comment. :3 hopefully that help :D
A diet that can lower your stress looks like something with a lot of fruits and vegis. Making sure you get a least one hour of exercise a day. Plus drinking tons of water and a some juices. Foods I'd consider would be pineapples, strawberries, bananas, cucumbers, carrots, and etc.
C. aggressive
In general, those who are passive don't speak up for themselves and let others "walk over them." Someone who is assertive will speak up and set healthy boundaries for themselves, but does this in a non threatening or harmful manner.
