Research report on the importance of opposable thumbs

1. What tasks were most difficult and why?
I found doing my homework or writing with a pen or pencil was extremely hard. It was hard because I couldn't hold the pencil. I had a hard time sharpening my pencil. It was hard because I couldn't turn it and it was hard putting the pencil in the sharpener hole. Turning door knobs was difficult as well because I couldn't use my thumb to hold it. I couldn't tie my shoes when I was trying to go outside because I needed my thumb to hold the thin laces . It was hard for me to turn the page in my book without my thumb because I couldn`t turn it accurately, I was turning it in random pages.
2. What techniques did you use to get around these problems?

It took a long time because I made a lot of mistakes. Sharpening a pencil was also very hard. I had to pick the pencil with my mouth then slide my eraser from my desk to my hand. Then I had to carefully use my mouth to direct the pencil into the sharpener hole, after that, I held on to the pencil to my mouth very tightly and turned it with the my palm. When I tried to go to the washroom or to my room, I noticed it wasn't so easy without my thumbs. To open the door I had to push against the knob with my palm then I had to move it to the direction it takes to open. I wanted to go to my friend's house to do a project and I decided to keep doing the experiment. However when I was about to go out, I couldn't tie my shoes no matter how much I tried, I couldn't tie my shoes so I had to wear my sandals to his house. When I tried to read a book I couldn't turn the pages so I had to turn the book upside down and use my other four fingers to turn the page.
