Another easy fitness test: put on your socks while standing After the recent post of the health test of the Brazilian physician who let's people sit down und stand up, many fatties complained that they have knee issues so that's impossible to do. So another easy method to assess their fitness is to ask them to put on their socks while standing freely. That doesn't hurt your knee, so it should be an easy thing to do. You just need basic balance and mobility, which a fit and healthy person should have, right? Lift one left, while standing on the other, every kid can do that. Also, since getting up without help is an impossible thing to do, how else would they do it, right?
