I guess it's good to spot your own lack of variety amongst your characters. Maybe now you'll make some old folk, baby folk, hip folk, fit folk and maybe even fat folk. Give your character design skills a challenge.
You do know I draw babies, fit and fat people all the time right? I mean, my fursona is fat even. If you haven't seen my art before now, it's just a little weird to say that without checking, acting like it's not something I draw.
