First of all, thanks for all the responses!

I'm a little older than you and I wake up most mornings aching whether I've done anything or not. Welcome to life as an older fart.
Excuse me, I prefer seasoned fart.

Bunch of youngsters all up in this thread. I'm 61 and, while I have my share of aches and pains, I'm still going strong.
Your reply really gives me encouragement because I admire your work so much. Your work certainly is ageless.

I turn 56 this year and still enjoy the pace. Morning after feels like I've run a marathon and in a way, I have.
You know, one thing this thread had reminded me, that I was forgetting to consider, is that any hard work is going to make a person (of any age) feel some kind of after-effects. Considering all that the shoot includes, now I'm feeling pretty good about how I feel the day afterwards!

I'm 30 and I have a chiropractor and massage scheduled every few weeks! lol

)) I have wedding hangovers the next day when I can't move my arms and legs after a full day of shooting

) My joint hurt and I'm so thankful I found an amazing assistant to carry my bags because my back is acting, too. Ugh...haha

Yeah, there's a local photog couple who are very popular & I went to a seminar they spoke at & they get a massage either before or after every (EVERY) wedding they do. I think that probably helps ease the pain a lot! I def make sure I get my chiropractic adjustment each month.

I'm 58 and my wife is 56. I usually carry a minimum of 2 cameras with flashes and a small bag with extra cards, batteries, etc. When I was 21 I stayed till the end of the reception, now I struggle to stay till 10:00. I've had a heart attack in 2006 and I have a disease where my back and neck is fusing into 1 solid stiff rod, but I still keep plugging away. Down to about 18 weddings a year from 40+ when I was young.
My wife usually has 1 camera with her. It kicks her butt also. She has bad knees and hips. But we both keep active all day, always moving, averaging 1500 images per wedding.
The thing that concerns me more than the physical aspects of wedding photography, is how much longer are young couples going to want 2 old folks shooting there wedding. We are current and young at heart, but I think our age is what is limiting our bookings. That, and the fact that there is at least a dozen new young photographers getting in the biz every year here it T-town. Charging rock bottom prices and taking all the pictures at weird angles.

Wow, Ed-- you & your wife are two tough cookies! If you guys can cope with the difficulties you have, then I should be able to keep going with no problem! I feel like I should stop whining now.
On the issue of not attracting couples becuase of age, I suppose that could happen (& I will find out if I keep at this long enough!) but I feel that if a couple chooses to interview with you because they love your work, that's what they'll base their decision on. If you can confidently tell them you can deliver the same quality & style of photos they've looked at & love, you'll be fine.

Providing you can manage competently with the equipment you use and you are physically able to keep up with the pace you are fine.
Hey I'm 33 with a back in the state of a 70 year old (I have had a severely prolapsed disc since I was 19 and sciatica). I have arthritis, carpal tunnel and ligament problems in my right wrist and need another surgery when I can fit it in (my fifth on that wrist) and recently had had the left wrist operated on last year for numerous things. Whilst I can still manage the job physically though I will continue with it (just be aware of any limitations that you may have).
Oh an before anyone wonders how I hold a camera... I can manage an DSLR just fine as the weight of the equipment keeps my wrists fairly static. I cannot however use a point and shoot or camera phone to save without major camera shake.
Another inspiring story! Rock on, dude.

Oh, sorry. You already said you worked out... Either way, I think you can keep going as long as you choose. And when the time comes when you choose not too, it will probably be because you have something else you'd rather do.
Besides, does it always have to be weddings? What about mixing in some easier portrait work. Half of business is selling yourself anyway. You never know, you could hook up with something you never thought of to make some cash.
You hit on something I brought up when my husband & I were discussing this-- branching off into other, easier areas of photography if weddings gets too hard. Up til now it's been kind of hard, becuase I've had a 30 hr week bank job so it only left weekends, which, of course, are taken up with weddings, engagements, bridals. But as of Sept. 9 I will officially be a FULL TIME photographer
so that's why this discussion has become such a hot topic for us. I'll be giving up full time benefits, so it's a big deal, but the benefits we'll get as a family we feel are more important (more time together, more time for oue spiritual activities, less exhaustion from me doing basically 2 jobs). Anyhoo, I digress; the point was I'll soon have much more time during the week to accomodate family, children, and senior sessions, which could become an avenue, hopefully, of enough income to replace weddings if they become too difficult. I really hope that's a long ways off, though, because I really love the energy & excitiement of wedding shoots, regardless of the ensuing exhaustion!

^^^ 'as above'
I too started late I am 54 and started doing weddings at 51. My daughter assists me and she also is exhausted the day after a wedding . She is half my age.
Well that has to make you feel pretty good! Good for you!

I've been taking my 13 year old Grandson and it really helps. He is a heck of a photographer. He loves taking the ground level shots and the 45 degree angle stuff that seems in vogue. I usually use several of his shots, he carries equipment and I pay him $75. This is definitely a win-win situation.
I have a 10 yr old grandson, maybe I need to start his training!

I'm 51. And while I view weddings as a young man's game, I still have a lot of years left in me. I'm pretty physical when I'm shooting and I'll start to feel my back getting tired midway during the reception, but I usually feel pretty good the next day.
I think about transitioning to portraits one day where I have more control over the schedule and pace and the work is broken into smaller chunks. But for now, I'm more than happy to get out there.
You're another one whose work inspires me & I'm surprised & encouraged to know we're in the same age bracket. Sounds like our thinking on future possibilities is similar. Thanks for the post!
