One in five Americans are concerned that the world will come to an end on Friday.

Besides that, nearly 70 percent are worried about losing digital copies of family photos if the lights go out permanently on Friday.

There was also an online survey that polled over 3,000 adults about their end-of-world regrets.

It found that one in 4 men said they would regret not having more sex if the world does end, while only 1 in 10 women expressed the same sentiment.
