To all you 'young 'un's' out there, it doesn't have to be like that.
I'm 63, I worked a physically hard day yesterday and was taken out by my beautiful best friend to the local tavern for beers and a meal after completing some painting for her. Coming home later in the evening I had a smile on my face and a happy heart. I've had my share of sadness and disappointments but don't let them linger around you. Enjoy what you have in the moment.
