Haber has also discussed the strong continuities within the philosophy of the anti-aging movement, writing that "For Steinach and Voronoff, as for the members of the A4M, old age was a "grotesque" disease that could be scientifically eradicated through the correct combination of hormones, diet, and surgery."
Haber还讨论了抗衰老运动哲学的强烈的连续性，写道：“对于Steinach和Voronoff，以及A4M的成员来说，年老是一种‘怪诞’的疾病，可以被科学地根除，通过激素、饮食和外科手术的正确组合”。
