80+ years could be the worst stage. My grandmother up there, is the last surviving of 7 siblings, widowed, and has outlived all of her friends. Her mind is starting to go, and she knows it. We can't show her old pictures, they just make her start crying. She's clearly depressed 24/7. Luckily for her, she has a deeply caring family.

Let me tell you guys... Nothing worse than being old and in pain all the time and neglected by any family. A baby doesn't know nothin. An old lonely person lying in bed all day sore all over and on a million drugs that make skin itch and sleep impossible... That person knows. That person only lives because of a shread of hope they they hold onto that some family member will remember them and hold them. They really need a hug sometimes and to be told they are loved.

Please be good to your parents and grand parents. Only degenerate trash people ignore the elderly.

An old person. I'm watching my grandma losing her words and thoughts delving into the past. My grandpa's been gone 2 years, her friends, her parents and sibling gone. I feel helpless because i can' t take away her pain. All i can do is care for her and keep her out of the hospital.

4 years old, you’re at the cusp of “you can be anything you want to be if you try hard enough,” to going to kindergarten. School starts, you’re getting picked on and yelled at by your teacher, and having your parents yell at you telling you can do better, or was that just me?

Dead.

Every stage sucks for some reason or another

Depends what you mean by worst. Old age is worst to me because it's so close to death and end-of-life ailments, but, it's also when you have the most wisdom and appreciation for life. Baby is pretty bad too because you don't remember anything, and you aren't old enough to be able to appreciate the fact that you have your whole life ahead of you.

One of those.

Unless you have medical problems there is no worse, there is only different. Life is 'memories' and a good life is family. First you are the young and spoiled, then you are the teen with only self made problems, then you are the adult to enjoy your children BUT have to worry about their safety, Then you are the grandparents to spoil the young for only a short time because you have to die to make room for the cycle to start again. The answer is, the young adult having to make a living and raising children has the greatest pressure.

Fetus, can be legally killed for no reason.

Depends. Men, younger than 30. Women, older than 30.

Teenager.
