The red pill allows you to shapeshift, but only into things as small as a rat or as big as an elephant. You can change your race, body shape, even your gender. Any permanent marks you've had on your body, like tattoos will vanish. Serious injuries stay, however. The changes will simply be physical, this means when you transform into a younger version of yourself or someone else, Your body looks and is younger, but you will still die of age as if you have never transformed in the first place. Your brain is not affected, this means you cannot be smarter by transforming into a genius, but it also means that if you transform into a bird you will not have the intelligence of a bird, you will always have your normal human intelligence, in short, your intelligence cannot increase or decrease due to transformation. You can heal minor to significant injuries to some extent with transformation; the more serious ones cannot be healed with transformation.

The blue pill allows you to be completely self-sustainable. You no longer need to eat, sleep or even breathe. As well, your aging process has ground to a standstill. Your rate of healing is also heavily increased. As long as nobody drops a piano on you, you are effectively immortal. As a side effect, you no longer take pleasure from eating, sleeping, or breathing. The blue pill also negates the effects of traditional surgery, because as soon as they make an incision it heals up, it also removes things such as shrapnel or implants from your body.

Taking either pill would be a life changing miracle, however, you can only pick one. Mixing both pills in your system would result in a poison that would kill you instantly. Choose wisely. The Blue pill's healing is not strong enough for you to survive the poison of both pills.
