Well yes, but you need to be smart about it, just like about everything else in life. People read full body workout and start some super intense training regimen which for some may be great, and for others it may be too much. Instead its more like some gardening efforts - every day a bit, not too much. My late grandparents are an example - obviously no smoking and absolute minimum alcohol and 0 other drugs ever, regular good sleep, and garden (plus a bit of nature which was just walks or foraging mushrooms). Understanding how body degenerates with age and injuries, especially joints and connective tissue. Workouts great for 20 years old are sometimes pretty bad for 40+. Don't stress heart too much, just enough, for long periods. Plenty of weightlifters who have messed up their shoulders, spines, knees etc. although at their peak they lifted impressive weights and looked accordingly. Guess what, this adds 0 in longevity, whatever effect was there is 100% gone in 5-10 years from all tissues and bones as cells fully renew, and messing up core of your movement can easily negatively impair lifespan.
