Excuse 1: "The fuzziness in the air is the light in your retina"
Response: "Well, how come there is more fuzz around people than in the air?"
Excuse 2: "The pressure you feel when you have a Ki ball in your hands is just what happens when you hold your hands in the same position for a while"
Response: "What about the heat,tingling and fuzz then?"
Excuse 3: "When you fire a Ki blast at a wall, you fly back because of the way you are standing"
Response: "Watch...(Fire a Ki blast at a wall and try to resist going backwards)." This isn't possible because the force eventually piles up and gets stronger than you.
Excuse 4: "This Ki stuff is a load of crap"
Response: "Why is there over 1,000,000 websites on it and over 3,000,000 people training with it then?"
Please send me more excuses you have heard and I will put them up here.
