I have an idea for alex: take a picture every day in the same position.
1. draw a line in a windowless room
2. keep a lightbulb in the same position
3. keep a camera on a tripod.
Make sure the conditions do not change.
Alex should take a picture every day with the same expression as possible.
After 10 years of photos, you can see how Alex appearance changes reliably.
This will take only 30 seconds a day, and maybe 5 minutes every month to upload the photos.
Yes i like the idea, its like what these guys did, watch the clips, there are more, good to watch..

I must admit, you don't look 37. You look more like my Korean friend Nate who's 22.
