I like to follow the social media pages of shared-living spaces I've lived in the past not just for reminiscing and memories, but because it provides an interesting tracker of general health over time.

The 2 group photos below popped up on my instagram feed back-to-back today, each posted within the last 24 hours.

One is from my college fraternity house in Seattle (on a beach trip with a sorority), the other is from a popular backpacker hostel in Queensland, Australia.

These 2 demographics (college kids and world-travelers), are more than any other I can think of, well-known to be predominantly full of good-looking, active, fit young people.

What do you notice?
