Has turning 40 changed your outlook on life in any way?

I will be 40 in another week. I did not think it would bother me. But as it is hurtling on I am getting extremely anxious. The thought is it is closer to fifty then sixty a pensioner and then death. How morbid is that. I still feel y and get sooooo horny with my husband but it isall going to end at some point. I remember as a child thinking my parents were disjusting as I knew they still did those things. At whaage does your libido go and you become obselete so as to speak. Could you imagine never having those feelings ever again ME JUST PANICING AS I AM TURNING FORTY 40 40 40 WHAT A NIGHTMARE
