And then we've had people up in their 80s and 90s doing very well with collagenate, especially because as we get older, we're really noticing the loss of collagen. So a lot of times with the skin, hair, nails, we have a lot of elderly people that do very well with collagenate and helping their skin to be thicker and so they don't bruise as much.
