Suppose a friend is always tired because she stays up late watching tv. which factor is having a negative influence in her health

the gravitational force on an object increase as the mass of an object also, im not going to report you, but this question should be under the science category, not health

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
