The current state of affairs is certainly abysmal. Some live over a century, while others die in their childhood. We age before we die. I'd rather die at 75 with a healthy body rather than dying at 75 with 10 years of senescence behind me.
So, a better system (should it be possible), would be to get rid of senescence. Even better, we could get egalitarian about death: no involuntary death before age X, at which point you die instantly. Sounds horrible? But it would be much better than the current system, where we let chance decide on the number of years we can live. Plus, you can actually make preparations for your departure.
So, what value would you chose for X? And of course, it would apply to you as well.
