Context: However although I ' m typing almost as quickly and accurately as normal , my brain is tiring and so I ' m trying to limit my typing to short bursts and then do something completely different ( such as sit down with a drink , or weed the garden for a couple of minutes ) before returning to it . This just about works , but I ' m still fairly exhausted . I just hope the tiredness is because my body is throwing all its resources into healing my finger .

Question: Why is my finger healing ?
Options:
0. Because my brain is tiring .
1. Because I ' m typing almost as accurately as normal .
2. Because I ' m typing almost as quickly as normal .
3. None of the above choices .
Answer: 3
