Are there age limits to Cosplaying?

Something that's been bothering me lately is the age limits to Cosplaying.

Say that you're forty or fifty and you still enjoy Cosplaying, are there any age limitations or could you still continue doing it until you die?

I mean, one of my biggest concerns is that if you're over fifty or forty can Cosplaying still be alive for those people even if they are much older than the average young Cosplayer? I often worry that their skins will show and it will be wrinkly or crippled and will receive tons of hate and hurt. I'm not saying anyone in particular is still Cosplaying but I am just overly concerned about this fact.

So, what are you opinions over it? Are there any "age limits" to Cosplaying or not?
