i forgot to say that I have a bad knee from an injury from a couple of years ago. I am only 15 years old and I already have limitations for exercising. Yeah so sometimes in gym when we do a lot of stairs or run a lot or when I just exercise on my own, my knee starts to hurt. In gym when we run the bleachers, I dont do it. Today we were just walking them so I decided to walk them. Now my knee is bothering me.
I do suggest you see a doctor...
because i am sitting with it at a funny angle
Because you're probably old, overweight, and don't exercise.
synovial fluid and cartilagr are not in normal reguired level and it is the beginning of ostroporosis
because lactic acid builds up if you don't exercise.
See a doctor. No one can answer this without seeing you.
More bone usage going down, More musle usage going up.
A cow can climb up stairs but not down.
You can trip and that can really hurt you in many ways you can even break a bone. Trust me i know because i triped down the stairs a week ago and i got a big bruise a sore wrist and one ankle hurt and the other got sprained.
A slinky (of the correct size) can walk down the stairs.
cause when you walk up it is easy and it is hard to walk down cause you can fall
Cows and bulls can both walk down stairs, as long as the stairs are wide and long enough. Some dairy sheds have stairs for the cows to walk down if the shed is on slanted ground.
no
They need to have knees to walk. And to swim. And occasionally to bend down and drink.
I've just been taking it and my knees hurt but not sure if it's related, I can walk okay but they feel weak, a little swollen and I can't kneel down, feels like my quad where my thigh connects to my knee has shrunk.
walk down them
Have a sim pick them up then walk down the stairs and set them back down.
some animals are afrade of heghts
