Answer:
Won't "weaken" your hands.
Step-by-step explanation:
Typing is easier for your hands. Having to write all day could take a toll on you. Your hands start to cramp and hurt once you write too much. With typing, you can do it quickly and won't hurt your hands. At most, you'll probably shake your hands then get back at it again. With writing, you'll shake your hands then take a break until your hands are ready to write once again.
