What would be the main differences (physical or otherwise) between two average, healthy males in the prime of their life, one born today and one born in the 11th century?

Are they different ages? Different weight? How wealthy would they be?

You really, really, really need to specify the question. Where is the 11th century man from? Where is the 21st century man from? What do they both do for a living? How do you define prime?
