Evolve into Mammal -> Get Spine -> Become Bipedal -> ??? -> Profit aka Straight Back (unless scoliosis gotcha)

Bend the other way

There are some exercises to do that. From yoga to HIIT. If you're too lazy to go to the gym you can find them online on youtube.

Not sure, trying to work on that myself. Every now and then when i notice im shrimping I will pull my shoulders back (pinch my shoulder blades together i guess?) and that helps relieve some of the tension in my upper back and shoulders

🤷 I don't know how to have a human body. Good luck to you, though.

Work on strengthening your core muscles. See a chiropractor, also.

Go to a gym and ask the person responsible what should you do

1. Be old
2. Back hurts
3. Forget to straighten out anyway

yoga and weight training helped me alot

flexiblity and muscles are needed. otherwise u will just try to get rid of a bad habit without having the stamina to do so

Chiropractor

I wish I knew. Oh, wait, it wasn't a metaphor..

have you been deveined? OK OK seriously, I think they have exercises that are supposed to help with posture and whatnot...or, they also have shirts and bras and other wearable deals that are also supposed to help
