Too old to party?

For the longest time I've haven't partying till the morning. I'm so dry up now. I'm old and to realize that I have to go through all this pain when I'm at my age now is hurtful. If I'm young I might be able to carry on. When a person is old, he tend to expect the most out of something because he is too tired to start all over again. Sorry to say I'm the one will bad luck.
