He looks tired to me too. I thought that it may be late nights and may be excessive drinking too as he always looks puffy.I'm sure Tom is a lovely chap btw. I'm not questioning or commenting on his personality, just his look of sleepiness. To me, he always looks like he has just woken up. Probably the narrow eyes, nasal voice, and deep nasal labia lines.
