You are going to die in 10 seconds...
...what epic words would you say?
I think I'd go with something along the lines of:
I’m tired of wondering if there’s something beyond this life. I’m going to find out once and for all.
Wait here, I’ll be right back.
Or maybe just loudly count myself down from ten and then do a Marianne Cotillard in TDKR. That would really fuck with whoever I was with.
