If you exercise and eat well, the worst of the effects of aging will be mitigated. Many people remain fit and active well into thier 90s. It's really about a life of effort: physical and mental.
Get fit and healthy now while you're young. Take care in finding someone you love and enjoy being fiends with, who shares your values. Grow old together and remain healthy so your lives aren't filled with misery.
It's not as good as staying young forever, but in lieu of that it's quite enjoyable. I'm 40, in good shape, and have been married to a lovely woman who also stays fit for over a decade. We're growing old together and it's very nice.
Protip 1: as you get older, the age bracket of people you find attractive moves with you. There's no way I'd actually enjoy a 20 year old now. Their bodies are fresh but thier inexperience and immaturity is a turn off.
What you want in aging is "compression of morbidity", meaning staying healthy and fit right up until the end, where your metabolism breaks down within one or two years and you die quickly.
Protip 2: find a fitness activity you ENJOY. That's the hardest thing about remaining fit. Unless you're one of those people who really likes the gym, you'll never stick with the gym. I like long-distance hiking in the rocky mountains. My wife likes historical European martial arts (longsword fencing). This is how we're able to keep in shape: each 'workout' is a good time we're looking forward to.
