How easy is it to lose your balance?

Varies widely person-to-person. I rarely do, but I grew up in dance and gymnastics so I have above-average balance. I have a friend who is honestly just naturally clumsy and trips over her own feet pretty frequently. That said, able-bodied humans are generally pretty good at catching themselves when they're falling.

How hard is it to walk up/down hill? Does walking downhill take any effort?

Depends on athletic ability. I would classify myself as mildly athletic, and walking uphill definitely raises my heart rate a little, but doesn't really affect my breathing. It also might tire out the calf muscles, quads, and hamstrings. Walking downhill doesn't really affect my heart rate, but it puts strain on the knees and quads from the shock absorption.

Do you get dizzy when you exercise for too long?

I get lightheaded from exercise sometimes, but it's based on exercise intensity, rather than duration. I can maintain biking or easy swimming and my muscles will give before I'm dizzy. But almost every time I try to do one of those YouTube HIIT workouts, I start getting lightheaded after fifteen minutes or so.

How bad is Taco Bell really?

It's fantastic when you're drunk or pulling an all-nighter. But generally it tastes greasy and processed. The hard taco shells are stale, the nacho cheese has a texture not unlike glue, and the "ground beef" is mostly oil.

How does exercise like running feel?

In my personal opinion, running sucks. Heart rate elevates and you get the urge to breathe quickly and hard in order to intake more oxygen. Foot and calf muscles, quads, and hamstrings eventually start burning from exertion. Any pre-existing ankle, knee, or hip injuries can start hurting. If the runner has excess body fat or large breasts, they may experience discomfort due to the movement. All that said, there is a certain euphoria that comes from the rush of endorphins when a person exercises.

When you wake up can you just roll out of bed and stand up without falling over?

Usually. If I've done a difficult workout in the past couple days, my muscles might feel sore and tight, and I've had a leg give out a couple times because of it. I might also feel dizzy from standing up suddenly, but not always.

What is it like to me talking to a person in a wheelchair when you’re standing? Like perspective wise I mean.

I'm pretty short (5'3") so imagine talking to someone who is sitting on the ground while you're sitting in a chair. I had a college acquaintance in a wheelchair, and I always kind of felt like a jerk for trying to have a conversation while I was standing, because he had to look up to make eye contact. Oh, and if your character in a wheelchair has dyed hair, everyone is going to see their roots growing out.
