When your fingers are too big to hold a small nail when hammerring, try to get a fork or a small comb to hold the nail.

If you have a problem opening jars or bottles, try some of the following methods:

- Try using latex dishwashing gloves or rubber computer mouse pad as they give a non-slip grip to the jar lid or bottle cap, or 

- Tie some rubber bands around the lid or cap, then cover a cloth over it and turn, or

- Turn the jar or bottle horizontally, carefully run some warm water over the lid or cap. The heat of the water will expand the lid or cap.

- Do not overload the refrigerator.

- Keep refrigerator away from direct sunlight or any other heat sources.
