DH is twelve years my junior. I'm not sure why, but most people seem more comfortable with the idea of a younger woman marrying a younger man, so I often brace myself for a negative reaction. For us, it was obviously crucial that neither of us wanted children. I will admit to some unease with the age difference as I worry about what the future will hold for us as I age well in advance of him. It is an added incentive to stay active and healty--to the extent I can control such things. Sometimes my body doesn't want to cooperate and tha'ts frustrating. I do know that I already have a leg up on many of my peers in terms of fitness, and my attitude about aging and retirement is important, too. DH's parents had him when they were older, and they're setting a fine example (as is my own father) on how we don't want to live post-retirement. They just seem so much older than they actually are, both physically and mentally. They've allowed their worlds to constrict to almost nothing other than trips to Walmart and the occasional group tour vacation. Granted, I should try not to judge, but it's hard not to see their current lives as the sum of a lot of other decisions. Decisions about fitness, activity levels, friendships, and personal fulfillment. I want to be very deliberate in how I approach the next thirty or more years of my life. I don't want inertia to set in, and I sometimes think having a younger husband will almost compel that.
