The 32-year-old actor worries about wasting time in doing something which he may regret later in life, reported Contactmusic.
"I have terrible fear of wasting time. Who knows? Maybe I should relax a bit. Maybe working too hard is wasting time. I have a fear of regret. I'm not afraid of death, although I know that sounds odd," Hiddleston said.
The actor became popular with his portrayal of mischievous villain Loki in Marvel's "Thor" and "Avengers" movies.
