Thats fair

I'd upgrade my ass so that I didn't need to shit, it just like teleported the poop somewhere

I'd upgrade my balls so that they aren't vulnerable when being attacked. That way I can steal Bobby Hill's purse and get away with it.

Can we pick the nature of the upgrade? I want to pee champagne
- From now on you're french
  
  Merde!

Definitely my spine. There's a reason basically anyone who has worked in the trades for a while has a fucked up back. It would be nice to avoid my impending back problems.
- Is it a form problem?

Probably brain, responsetime
Who am I kidding, it’s gonna be vibrating dick
- Good newss! If you use a massage gun pressed right to the base of your dick, it vibrates like a vibrator.
  Great trick if she's on top, fun for everyone
- I think somewhere on the internet there is a whole ass manhwa based on this concept

All y'all are picking dick.
But the correct answer is the balls. Need something more durable and with a faster reload time.
- Then you want to upgrade your prostate, not balls.
- How many times a day do you need to jerk off?!
- that's okay my homies can hook me up with a reload
- You'll be limited by shaft resilience before reload time, especially over multi-day operations.
- Careful with that, you probably wouldn't want to end up in a StuG III Ausf B situation
  
  rubbing a monkey's paw
  Oh no! I didn't realize I was asking for Nazi balls!

Classic.

Skeletal structure.
This implies stronger bones and stronger joints. With a stronger framework to hold your muscles, you get a sturdier body.

I would like a second of the same dong. undecided as to configuration (over-and-under vs. side-by-side)
- Under/over of course.
  \ You can be a one-man DP

better brain
with that I can make more money and with that I can just buy new organs
- Congrats. You now feel anxiety twice as intensely.
  
  yeah but now I can buy 2x the anxiety meds because of all my money

Sometimes I wonder if my brain was already donated.

I asked the lady with no legs. She said bigger dick.

Heart failure is one of the biggest killers out there. I think you'd have a better odds of living a long life with some kind of super heart. Your heart is basically just a water pump that has to remain online for 100 years or you die fast.
- That's a good point, but in my opinion the other common deaths are way worse. Cancer? Living with the anxiety of impending death and constantly getting sicker, more in pain and being nauseous from medication? Or COPD, feeling like you are suffocating slowly? Alzheimers, Parkinsons? Or my personal fear - dying from a stupid simple cold? Man, I take a heart attack any day of the week.
  
  Yeah, I'm just thinking about the meta pick for general longevity.
  
  I have a friend who's losing the battle with cancer right now and I didn't really appreciate how bad it would be. Both the cancer itself, and having this much forewarning. I would rather it be quick and surprise. For my sake lol screw everyone else
- Unless your lungs fail
  
  The heart will take that on after the lung layoff.

Upgrade my liver, stay drunk for the next 3 years and 9 months.
- Wouldn't being able to enter a coma on demand be more useful ? Wake up in 4 years...
- Isn't that backwards? The liver filters alcohol out of the body. I would think an upgraded liver would sober you up quicker.
  
  But I'll die.
  I guess this isn't a good pick.

Having a bigger dick is overrated. Great for fantasy, but very impractical.
I'd upgrade my lungs to be better filters and oxygenate my blood. My immune system to fight diseases my efficiently (turn it into a scalpel rather than a cluster-nuke). My brain to retain it's learning capabilities well into my later years. Completely overhaul my metabolism so that I won't have to do heavy exercise to get good muscles (really, all that exercise just exists to make one chemical reaction happen).
After that, then, only then, might I consider doing something with my dick. Though perhaps more with my balls, so I can just switch off the reproductive capabilities to ensure safe sex.
- It said one organ, you went on a shopping spree haha.
  
  Hey, flesh is weak! :V

I already have a big cock. So I would choose a bigger cock.
- Hey, spare some cock for us too!
  Hmm i think i worded that wrong...

My brain, i hate being neurodivergent it'd be so great to just fOCUSSS
- It's funny, there's a local TV program where people can anonymously ask adults and kids with various handicaps questions they wouldn't dare ask them directly and "would you rather not have it" is always one of them. The adults always dodge the question by saying that it's not as bad as it seems and so on and then the kids always reply like you did "I would much rather not have any issues!"
  
  The adults: I learned to live with it and now it became part of my identity
  The kids: this sucks! everyone's mean to me and the world makes no sense!
- I'd upgrade the depression away from my brain and give myself the ability for hyperfocus at will and to turn off sensory issues. Taking the autism and ADHD away altogether would leave me a different human, idk that almost feels like dying a little bit, or being lobotomized. Wouldn't want to lose a part of my brain that makes me me. But super valid to want to be neurotypical!
  Thinking about it, if it counts as an organ, idk if I wouldn't rather change my immune system to stop attacking healthy tissue and get better at attacking viruses instead. Tough choice.
- monkey's paw curls
  
  When a monkey's paw's last wish is spent, you have a monkey's fist.
- The only upgrade I want is to be able to control the hyperfocus
- Me too with brain, I hate not being able to socialize.
- Considering what it means to be "normal" around me, I'd rather be divergent.
  But then again, I manage to focus well enough.

Banger post. Deaf community goes hard
- Sorry, can't hear you over my massive dong.

my skin, i think the one organ that protects all the other organs is long overdue for an upgrade

Sinuses. Those fuckers are overdue for an upgrade. Can you imagine never being congested again?
Brain is the right answer but sinuses are #2.

Gosh, only thing I can think of is self-repairing telomeres.
Everything else is perfect, might as well live for hundreds of years.
- Everything else is perfect? You don't have joints?
  
  My joints are as good now as when I was 21, and they are supported by my broad range of glorious and balanced musculature.
  
  Just an immortal pile of goo.
- I wouldn't be optimistic, something else may break

Can I just say “my immune system”? That’d prevent all kinds of diseases and make you cancer proof!
- not an organ and having a stronger immune system would kill you
  
  Post didn’t say stronger it said upgrade. And it wouldn’t be an upgrade if it killed me!

My stamina is shit so lungs.

My bones.
Also I checked, bones are an organ.

Deafinitly one of the choices
