You just need to refocus your mentality on not living for a future life, to enjoying this one!
I've difficulties reconciling with the fact of growing old
What's the alternative to growing old?? Being dead! I'll take growing old anyday. There is an upside to growing old, you dont' give a crap anymore what people think of you, you say what's on your mind with no regrets, you get to laugh your head off with your other "old" friends over how stupid those young people who think they are so smart, really are...you finally can have perfect teeth and you can be a pervert and people think its "cute".
