41... well that was 10 years ago for me.
As I heard somewhere, you are now a 'very old young man'. I am now a 'very young old man'.
All I can say is, Try and allocate your time wisely.
Try and make plans for the future, but never neglect the present, because it is always there, and you're living in it now.
Make sure you and those close to you, especially the older folk, have wills or something of what to do in the event of death or very bad incapactitation. Cannot stress that enough.
And for your own sake, try not to take those people around you for granted.
And if you find yourself wishing or thinking what life would be like if they were dead, odds are you will find out soon enough.
Most likely when you are not ready.
I don't envy you the path you're going through, but I wish, wish so very much I could go back to it again.
