There is nothing outside the realm of seeking out a mad scientist that you can to do change your genetics, in a positive way at least. Gene sequencing can be damaged by many things: excessive exposure to UV spectrum and higher radiation, carcinogens, free radicals, major physical damage, and aging.
Certain things can, however, affect your gene expression, specifically steroid and steroid-like hormones. Testosterone turns on certain signals for increased synthesis of certain types of protein, leading to increased skeletal muscle, increase in male characteristics, and sometimes a poorer blood lipid profile. Cortisol, also a steroid, does the opposite in many respects, and is required for certain stages of the healing process.
