Yes, I realized my balloons say "P0" instead of "40"... I didn't feel like re-filming this lol.

I turn 48 in August. Back in January I weighed 287 lbs. I got to the point that it was hard to walk. I was told I need a knee replacement. But no doctor would work on my at my weight. I decided to change my life. Started walking everyday. Lift weights 3 times a week. Eat right. As of this morning July 18th I  weighed in at 195 lbs. 92 lbs lost. I feel great and my knee doesn't hurt.

Happy 40 birthday Dave. Keep going and never stop, years are irrelevant 🍻 🤗

@geraldpolymath

Funny, I'm 54 and I'm laughing at this video.........I still feel good because I workout and eat right, Plus, remember the 5 pillars of longevity: weight lifting, cardio, stretching, eating healthy and sleeping.   Plus,       fun.

Happy Birthday! It is just a number, I am almost 42 and I am very close to my best fitness, I am saying "almost" because I was a PRO swimmer so its a bit hard to get back to that... But, I did my first Ironman this year and feeling very good:) 
Just focus on every day and do a LOT of FUN!!!

Happy Birthday once again!!!!

Have an amazing day!!!!

Happy 40th, the best is yet to come - thanks for a great channel :)

@MrHepcat34

Happy birthday! I’m 48. I thought I was going to be retired, and wasn’t gonna live past 50. My family started a business this year which clearly means I don’t plan on retiring anytime soon.  Running has fallen off the rails due to the demand of running a business. I truly enjoy watching your videos, and listening to your podcasts. They keep me motivated to keep working on myself.

@amircastilla07

Happy birthday. This year im 40 as well and have had to search deep for motivation but the good thing is im back at it again.

@tonydavis3796

Happy birthday! 40 is young! I was starting to feel life's pains in my 40s (joints etc), but switched to low carb and life is pain free in my 50s and I'm a lot leaner. I am running a 50km trail run next weekend while in ketosis. Don't need the carbs! Best to focus on fat and protein as we get older. (edited for typo)

@Gabrielerf

Happy birthday Dave, thanks for sharing your thoughts. Enjoy your beautiful Family.

@aliza6491

Happy birthday! I've been enjoying following you and watching your videos. You are doing so much at 40 that many are not. Comparison is the thief of joy.

@bradwoodley4406

Happy birthday. I am 51 and I do not feel it. You need to keep moving or you will get old!  My parents are still very active and raised me to be active in sports. They do not look or act their age either. Continue to be role model to your kids running ultramarathons chasing the summit and they will do the same.

@oilindustri

Happy birthday, glad I found your channel to go along DC and DesFit

@juanjesusascenciolango7736

no te preocupes, es solo un numero, y feliz cumpleaños!!!!!!!!!

@richriley8031

Happy birthday 🎉 Don’t worry 40 is just a number you can feel younger at any age! I’m in my 70’s but feel much younger at times!😊
