Age, health, earning power, relationships, jobs, fitness, are all variable. It's all how you arrange your time and priorities. Fat asses have the same 24 hour day as non fat asses, and they're exposed to the same sort of social situations as non fat asses. Don't get healthy for anyone but yourself. Balance is important, though, and, a bit of everything isn't all bad. We someone is overweight it speaks lack of discipline, lack of focus, poor education, and so on. Sure, there are cultural and money factors, but, even poor folks can behave properly when it comes to their relationship with diet and exercise.
Most often, being overweight is a symptom of a deeper mental health issue. Often, compounded low self acceptance. Only you can change that.
We all are going to get old. We are all going to die. How we choose to spend our lives is up to us. It's just that simple. It truly is.
I spent a year living in my car. I've survived open heart surgery without a heart attack. I give 40% of my paycheck every week to the government, and...I'm o.k. with that...but, you have to help yourself and take personal responsibility for your own physical and mental health. That means becoming informed. I've spent hours honing my crafts / interests. Research upon research. Daily, I build technology that affects millions. That's all by design.
Growing up; being gay...can be hard, because we beat ourselves up mentally. We get it in our head via false belief systems that there is something wrong with us. There isn't. "Getting ahead" is about strategic planning, marketing, work, luck, and social skills. Gay does not entitle you to be clueless.
With self acceptance comes more happiness; more comfort; less anxiety.
Exercise, and proper diet, are powerful anti depressants, and you're able to learn 20% faster than a fat, out of shape, person. You, though, have to take action. For yourself. Not for the approval of others, but, to be alive; feel well; live a long and happy life.
Being gay is no big deal.
