Lab rats

In primary school, if I can remember correctly, I was chosen to be apart of a long term research program that went y the name of LOOK. LOOK standing for lifestyle of our kids. The program mainly focused on out our growth an health (our fitness levels). So we were given pedometers, do the beep test a lot, planking, jumping and hand eye coordination activities. These were usually done at school bit there was more to it once we got to the hospital where we continued with getting blood tests, scans and x rays. Now after 4 or 5 years, they're back and I' m currently in the process of it all again.

Have any of you been a lab rat for experiments or long term programs?
