Jeff had always been average, so he figured it was time to become above average. He reached for his backpack, and extracted two baggies. There was Tyrone's jockstrap and Nathaniel's y-fronts. There were some advantages to working as the towel boy in the boys locker room. He carefully extracted the blond pubic hair from Tyron's jockstrap and the black hair from Nathaniel's. The Chronivac said it didn't need the actual DNA source, but the manual had indicated a higher probability of success with DNA samples. He put the blonde hair in the Chronivac DNA receptacle and scanned it first. Then he removed it and put Nate's hair in and repeated the process.
Tyrone was the star of the football, water polo and wrestling teams. He had been voted Top Jock at the school two years running. Nate was a senior, but had been taking classes at the college too. When he graduated in June, he would receive his high school diploma, his college diploma and his masters in Advanced Mathematics.
Jeff set the Chronivac to 50% Tyrone and 50% Nathaniel, and then ran the program. He tingled all over, and needed a shower. He kept expecting to see changes but he knew it would be gradual. He had the first inkling that it was working when he got dressed and discovered that his pant leg was now a half inch shorter than it had been. He was growing taller?
