Obi wan's age
Why does Leia quip that Obi Wan looks old enough to be her grandfather when he looks 40s tops. Her father (Senator Organa) looks and is about 20 years older than Obi Wan yet Obi Wan looks old enough to be an old man (grandfather)?
Obi Wan does not look old. He does not look like a young man as he was in the prequel trilogy but he certainly does not look like an old man.
Ps. Also, I'm a bit taken aback that simple raiders and thieves can punch and beat him up given how powerful he was in Ep. III.
