Dan came to to find he had been moved across to a chair. His mother was holding a glass of water "Here have a drink. You gave me a hell of a scare"
"What happened?" asked a still disorientated Dave.
"We put the formula X on your left arm and a placebo cream on your other. It's exactly the same as what is in the formula only without our special ingredient"
"Why did I pass out though?"
"I don't know. Maybe some reaction to the cream. We've taken note. You were totally out for about a minute. Do you feel different in any way?"
"No I feel fine"
"No burning on your skin or anything?"
"No perfectly normal" You looked at your arms. They looked the same as usual to you.
"Your sister is retrieving her medical kit. Stay here and rest. We need to check you out thororoughly. If there are side effects best we know about them as soon as possible"
"Side effects? I thought you said there was nothing to worry about"
"Neither of us experienced any side effects but it's always a possibility. Our ingredient works inside individual cells. It's a type of gene therapy"
Your sister returned. You spent the rest of the afternoon undergoing every medical test you could imagine. Your sister was a trained medico but had since completed a PhD in biochemistry. You trusted that she knew what she was doing.
You were finally given the all clear. Happily you returned to your room and your book.
