The fingernails on my right hand are noticeably bigger than those on my left, as are the toenails on my right foot. Is this a common phenomena? If I was left-handed would the nails on my other hand/foot be bigger or is it coincidence?
For your hands isn't it just because you are better at cutting the nails on your left hand if you hold the scissors in your right hand?
That argument fails though when it comes to your toe nails
