Ha ha. Yes, but it will likely take a while. I went out with my Brother-in law who is about 5 years younger than I. He was hauling everything he normally hikes with. I weighed his pack at the beginning of the trip at 43lbs for a two night stay. My pack was just over 21lbs, including the bear ball, with all the food. This was about 5 years ago. Last year he was down to 28lbs, for about the same trip. I still carried the bear ball, but he carried his own food, so I was down to ~18lbs at the start of the trip (including a liter of water, alcohol stove and pot.) I would have been lighter except this was later September with snow predicted in the hills, so I brought a 3lb/0F bag.
Over the intervening years he has gradually adopted lighter gear, as he has seen me use. He got some AM drops and got rid of the 3L platty canteen he carried. He got rid of his 5lb pack and got a 2.75lb one. He dropped the old Thermorest Guidelite (~2lb) for a Neoair I loaned him. He bought one. He got rid of the old whisperlite and got a Jetboil. None of these choices were GOOD. But, they were all a step in the correct direction. I applauded each change. He REALLY liked the G5 I had been using, but, I told him to wait. I had many repairs on the G5, and hopefully, he would find something in the 1lb range that would be more durable. I KNOW he will want the new Murmur. After a spring and summer of use, I will know whether to recommend it or not. He said he would look into a lighter bag. His bag is military surplus at about 5lb. After explaining about bags, he wants a good down bag, but, he didn't think his wife would let him drop $400 on one. The point is, he is an old boy scout and leader. When he said he would be back next year with a 25lb pack load, I believe him. Cutting his pack weight to less than half what it was took about 6 years, but, he now knows there is a difference in weights and WHY I carry such light stuff.
UL is more about TEACHING others that what they do can be accomplished with much less gear. It can be accomplished safer, with knowledge of what you do with the gear you have. It can be done more comfortably than with old style packing, less hip, knee, shoulder and back pain, less strain on your muscels, less work overall on your body. Our milage changed from ~1.5-2mi per hour to 2-2.5mi per hour with what savings he has made, some at my insistance. (Some "OK, let him carry it.") Only one weekend a year is enough to get someone on track. He only spens about 15-20 nights per year out, though. It is hard to do more than replace old or broken gear. And, it just isn't worth buying the best gear for UL travel. For example, his pack was purchased at wally world. 2.5lb is not bad, I will show him how to cut off extraneous bits of fluff and get it down to about 2lb before we go, next time. For $29, it is not a great pack but servicable.
