What do you think?
The best way to find out is to test! It is possible to test it at the Norwegian museum of Science and Technology.
I did an experimental design where I tested age, gender and sense (vision and hearing). My brother in law (35 years), my son (10 years), my niece (7 years) and I (41 years) were volunteers. We took the time we spent on registering sound and light.
My brother in law was a tiny bit faster than me when reacting to sound, followed closely by my son and my niece. For light my brother in law was fastest, then my son, followed by me and my niece. What does this result mean?
