Snake's age really isn't relevant- he just ages prematurely.
The widely accepted theory is that genes age; which means that Solid had genes the same age as the genes of Big Boss at the time of the Les Enfantes Terrible project.
So, if Big Boss was XX years old at the time of cloning, that means Snake had XX years shaved off' his lifespan before he was even born.
