How do I create texture that resembles texture of human body? Right now my human model looks way too smooth, in cycles render.  I prefer the bumpier look of Blender render, but I want to use cycles.  How can I create a bumpier, lumpier-looking human, something that looks more lifelike? Specifically, I want my good-natured wise man character to have a lumpy belly that ripples when he laughs! I am currently using diffuse BSDF node and a little bit of glossy BSDF node.  Thank you for help!

Edit: 
In response to atomicbezierslinger: I wanted to go ahead and say that yes, I do mean a protruding round belly, with slight rippling and dimpling, just enough to look like lifelike. This is the closest I've come to finding a photo reference, I hope this is not an inappropriate photo. 

Just slight dimpling and lumpiness.  I will see if i can find a better reference photo.  

Since you mentioned it, I would also like to know how to create fat folds that move realistically; that would come in handy for another character.  I appreciate all help and I will look into the SSS Shader.
Since it seems you found it useful, I am re-posting my comment as an answer:

For the dimpling use a combination of a Displace Modifier and some bump in your material. For the skin material add an SSS Shader to your glossy+diffuse mix. A skin texture image into the Diffuse color input would help too. For the ripple you can use a Cloth sim like in this tutorial. or a Soft Body sim like in this tutorial. Finally here is a Soft Body tutorial specifically for belly ripple, lol - although it is in Spanish. Good luck!
