When did I become an old person? Older person. Oh, a "mature" person. A senior citizen. What? I've started getting mail from our benefits department about my milestone birthday. Hold up there people!! I know they do that to prepare for you for getting ready for retirement and Medicare. It's still weird.
A long time ago I saw a little sign that said, How old would you be if you didn't know how old you are? That's a fun question. I think I'm still in my 40's somewhere. In my head. Now, my body is a different story! My body says, yep, definitely not 40's! I guess this is when things start to wear out. I'm ok with that as long as it doesn't hurt. I suspect that's why some 'seniors' are grumpy...they have chronic pain. That would suck. I injured my back putting up the Christmas tree, and for 2 MONTHS it hurt me. It's exhausting to be in pain all the time.
It takes longer to do things. Physical and thinking things. I saw some dumb humorous story about old people and bird watching - that when you're younger you could care less about the birds in your backyard. Then I realized, well of course! When you're young, you're busy making a life for yourself...taking care of your kids/spouse/partner. You don't have the time to watch the birds, or smell the roses. That's the part of getting older that I like. Now I have the time to do those things. Watch the birds. Watch the snow when it falls. Take leisurely walks. Spend more time cooking and trying new recipes. Reading. Learning new hobbies.
My brother said he misses all his friends getting together and the big parties at holidays and game days. Now everyone has moved away or they just don't do those kinds of parties anymore. I told him, of course not, they're all old now! You've already had that kind of fun. You can't party forever. It's a pain in the butt. Move on! "Fun" becomes something different when you get older. Lots of mature people find out that they like things they never knew they liked! Like reading, or doing puzzles, or cooking, or sewing, or gardening! Lots of mature people find out that doing some kind of volunteer work, gives them purpose.
As long as you're in good health, getting older is pretty great.
