keyboard arthritis

Arthritis ..?? However, it is written. lool?
I was wondering, what are some things I can take or do, or help reduce my chances to get severe arthritis? Each type I, or use the mouse, the joints get very sore, and my wrist cracks A LOT. And .. I'm only 15! My hands make me feel like I aged 900000000 … = / Lol Any ideas? Oh Yea, .. How can I prevent carpal tunnel? I use this computer much. I lift my wrist to not touch the keyboard and stuff. But this still does not do anything? <333 thanks!
Please go to the doctor for further examination, but if the joints problem with taking vitamin and mineral supplements to lubricate the joints enough. One tip not be with the team too much.
