"According to my findings your abilities can be triggered through synaptic impulses," Isaac stated.
"So all I have to do is think about what age I want to be and 'poof'." Sarah said, to which Isaac nodded.
"Well that sounds simple enough," she shrugged as she went to stand. Isaac stopped her asking that she lay back down.
"While it is true you can just change your age simply by thinking about it their are other ways that can trigger the cellular regeneration."
Sarah have Isaac a confused look as the doctor flipped through his notes. "Synaptic impulses can be triggered through thought yes," he stated. "But it can also be triggered by an emotional response. The synaptic pulses can be triggered by physical or even emotional stimuli."
"Define emotional and physical," Sarah asked wryly. She didnt like where this was heading.
"Well," Isaac said, loosening his collar. "If you were to become embarrassed orangey that would trigger a reaction."
"So I would literally turn into a brat if I have a temper tantrum," she sighed. "Or turn into an infant if I fart in public. That's just perfect."
"In time you could learn to control the synaptic pulses," Isaac said trying to sound hopeful. "The physical aspects though do have me concerned."
"How so," Sarah asked.
Isaac said nothing, simply reaching over quickly and tickling Sarah on her ribs. Sarah squealed, knocking Isaac's hand away.
"What the hell Isaac," she exclaimed. "You know I'm ticklish."
Isaac said nothing simply looking at Sarah. At first the spy was confused, before noticing her hospital gown felt a bit loose. Quickly grabbing a mirror she gasped as she looked at herself. "Shit I cant be more than 20 or 21 now!"
"It appears physical stimulation causes physical response that reduces your age by about 10 years or so," he said. "Pain, pleasure, even tickling will cause you to regress."
"So how do I fix it," she asked.
"Concentration mostly," Isaac shrugged. "Not focusing on the physical stimulation will reduce the amount of regression that takes place. However, once the regression takes place you would need to focus to regain your previous age."
"This isnt good," Sarah grumbled. "If I were captured, tortured..."
"Than your captors could simply cause enough pain to revert you to infancy," Isaac warned. "And considering nerve receptors are more sensitive in ones youth, you could find yourself in a situation even you couldnt get out of."
Sarah nodded, turning this latest bit of information over in her head. She was going to need to practice control before she started this mission.
