This couple volunteered in an experiment to see what each other would look like at 50, 70, and 90 years old, just one month before their marriage.
Watch their reaction on this video as they see each other age:
When they were looking at each other, you could see how much they were thinking about what good times and hardships they would have been through after all that time.
It showed the love and commitment they have for one another, and it confirmed even more to them that they were happy to start their lives together.
When people are young, they think they are invincible.
They never really think about how they will age, so this is a real reality check, something they will hopefully remember as they grow older together.
It would be a great experiment to do; I would volunteer for it.
