I will be 77 in a couple of months.

My sleeping and waking hours have changed gradually over the past few years, and seem to be set at: go to sleep at 8:30 PM, and wake up at about 3:30 A.M. I truly very much like my hours!
My day outside of the house starts at 7:45 when myself and my dear friend next door (also a widow) drive to weekday Mass together. Thankfully, neither of us have to use a cane yet, although we have joint pains now and then.
I am grateful that I can still mow my lawn with a key-start mower, and trim bushes and pull weeds, but no longer in the sun here in Florida! I wait for the shade. I no longer dig holes in the earth to plant annuals, or anything else -- I just do my best to keep things neat. I remind myself I am not going to take it with me!

My indoor garden is flourishing with plants that I repot, and root into new plants, and give them away when they are about 18 inches high.
There is a cactus plant in my living room, on a bench, and is about a foot and a half below the ceiling. It is tied to a wooden dowel to keep it from falling over! I think it would take three people with garden gloves on to re-pot it -- so I am just leaving it alone and watering it once a week.
One of my eight children, the youngest daughter, lives here in town with her husband and two sons. I see the others less, but we do keep in touch by phone and e-mails. Visits are great fun when they happen! 12 grandchildren now!
There is much more going on in my life that I am very grateful for, and I pray for the fortitude to accept whatever may be around the corner. God is extraordinarily good to all of us here in this temporal place! He can change the bad to good when we allow Him to.
I love growing old!
