Lloyd Bridges is 40 in this picture. He was born in 1913 and this is from a 1953 film... Mostly what makes him look old here is his haircut.

All the lead didn't help. And the playing with mercury in school. Actually, there was lead involved there, too, as I remember my dad telling me about how they'd put a piece of lead in their cup of mercury to see that it floated.

Also had a science teacher clarify that it was mercury oxide that made playing with mercury so dangerous, with the anecdote of knowing someone who tried to commit suicide by drinking a large amount of mercury, but then only ended up with the shits (and probably a few less IQ points from the mercury oxide vapours he would have inhaled while drinking it).
