What would this be karma?

wondering if this has happened to you. sorry this might be a little long. okay you start to grow into a young adult and you see people that may have let themselves go a little bit and say, i wouldn't ever let that happen to me, and it did. Or I didn't like to go to a certain denny's cause the servers in there looked kinda unclean, only now quite a few years later i have gained some wait and when i apply to be a server and don't get the job i feel discriminated against not that they'd say it but i know they want the young cute girls not the heavy over 30 type even though i have alot of experience in serving. I am not a mean person, it just seems weird that when i look back on my life things i've said or said i wouldn't do are happening. another example, i used to wonder why people let their teeth go (this was when i was younger) and now understand completely because nobody can pay for insurance like myself whose missing a tooth in the back and need treat the other ones that are hurting.Like i said i'm not a mean person maybe judgemental when i was younger and not appreciative, i'm learning alot especially after losing alot. If you only knew then what you know now!!!! That part was just in general
