I am 50 years old, can I still adopt a child?

Yes, lonely to be alone,, i have a friend too HE is 50 want to adopt 18-20 years old son, and to be his legal son, for me if there is no LAW we can adopted any time you know i'm still young i'm 19., year old i was touch by your question,, so we can adopt a daughter or a son as we want ,, that's why there's a LAW and privacy's of how to adopted, it helps us,, how to adopted,, how about if , We can adopt as we want or how old is he/she,,,,,, for me there's nothing wrong of how old are unless you cared about for your child that you adopted,then he will live you safe and secure, then you can provides the needs that he/she wants every day,,
