How does the use of a basic hand tool like a screwdriver affect your health?
a.) it increases your level of physical activity.
b.) it decreases your level of physical activity.
c.) it does not affect your level of physical activity.
d.) it lowers your risk of injury.

I believe the answer is: A.) It increases your level of physical activity.

Using basic hand tools would create additional burn of calories due to the movements required to operate the tools (such as hammering, twisting, lifting , etc) even though the amount of calories burned would not be as much as cardio or resistance exercises.
