Healthy ageing may delay, but not eliminate, the caregiving responsibilities of adult children. Care may begin later, change in nature or be shared differently among family members.

Cross-country evidence does not show a simple trade-off in which more older workers means fewer younger ones. It depends on growth, labour demand, institutions and skills.

Retirement ages were set for a world with shorter lives and different work. India's own ages, generally 58 or 60, are administrative decisions, not biological ones.

Nothing available today can reverse ageing in a human being. Some ageing markers have been reversed in mice, most notably in a 2020 Nature study where old mice recovered lost vision.

Slowing ageing, delaying ageing and reversing ageing are three different claims, and only the first two are anywhere near a clinic. Reversal has been shown in cells and in mice, not in people.
