<human>:  Was the son of Tsar Nicholas a daredevil?
<bot>: No, the son of Tsar Nicholas was not a daredevil. Tsar Nicholas had only one son, Alexei. Alexei had hemophilia and had to be carefully guarded. Hemophilia is the inability for blood to form clots, making any small cut dangerous. So the son of Tsar Nicholas was not a daredevil.
