My worst ticklish spot is just below my ribs... on my lower tummy ... i just can't take it for very long there. The first time I was asked to make a tickle video I thought "how fun.. but will I be able to physically laugh for that long? I'll surely die." Little did i know how sore my tummy would be the next day from laughing so much! Like I did 300 situps of something. Actually being tickled of course is the worst. That's when your body is screaming no please stop them and can't.
