In Kaliyuga, we human have a defined set of normal physical characteristics like height and weight based on the gender male and female.
Similarly, were there any mention of standard physical characteristics of a human, deity or other characters in the previous yugas? Is there a mention that all the people had same characteristics or are they different? Particularly in Mahabharata, Karna, Arjuna etc. did these characters have normal human heights and weights (like us)?
And also I read in some answers on this site where all the characters are aged below hundred years. Are these years counted in demigod years or normal human years?
